1 6603 107 TWO SISTERS WITH FAMILIAL MEDITERRANEAN FEVER: LACK OF CORRELATION BETWEEN GENOTYPE AND PHENOTYPE? FAMILIAL MEDITERRANEAN FEVER (FMF) IS AN AUTOSOMAL RECESSIVE DISORDER CHARACTERIZED BY ATTACKS OF FEVER AND SEROSITIS. THE MOST IMPORTANT COMPLICATION OF FMF IS RENAL AMYLOIDOSIS, WHICH DETERMINES THE PROGNOSIS. THE GENE CODING THE DISEASE (MEFV) IS IDENTIFIED ON THE 16TH CHROMOSOME. THE MOST COMMON MEFV MUTATIONS ARE M694V, M680I, V726A AND M694I LOCATED ON EXON 10 AND E148Q LOCATED ON EXON 2. UNFORTUNATELY, GENOTYPE-PHENOTYPE CORRELATION IS NOT WELL ESTABLISHED AND THERE ARE UNEXPLAINED ETHNIC DIFFERENCES IN AMYLOIDOSIS RATES. WE REPORT TWO SISTERS WITH A COMMON GENOTYPE (M694V/M694V) PRESENTING WITH DIFFERENT PHENOTYPIC CHARACTERISTICS: ONE COMPLAINING OF INTERMITTENT ABDOMINAL PAIN, ARTHRITIS AND FEVER, WHILE THE OTHER WAS SUFFERING FROM INTERMITTENT PLEURITIS AND FEVER DURING ATTACKS. THE OBSERVATION OF DIFFERENT PHENOTYPIC PRESENTATIONS WITH A COMMON GENOTYPE IN TWO FAMILY MEMBERS SHOWS THAT DIFFERENT PHENOTYPES CANNOT BE EXPLAINED BY PARTICULAR MUTATIONS. TO UNDERSTAND THE CORRELATION BETWEEN GENOTYPIC AND PHENOTYPIC FMF VARIANTS THE EXISTENCE OF COMPLEX ALLELES, MODIFIER LOCI, GENETIC HETEROGENEITY AND POSSIBLE EPIGENETIC FACTORS SHOULD BE STUDIED EXTENSIVELY.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
2 3381  25 HLA AND AUTOIMMUNE DISEASES: TYPE 1 DIABETES (T1D) AS AN EXAMPLE. AUTOIMMUNE DISEASES NEED TO BE CONSIDERED AT A GENETIC AND MECHANISTIC LEVEL. T1D IS AN AUTOIMMUNE, CHRONIC, MULTIFACTORIAL AND POLYGENIC DISEASE CHARACTERIZED BY THE DESTRUCTION OF THE PANCREATIC BETA-CELLS ASSOCIATED WITH LONG TERM DYSFUNCTION OF SEVERAL ORGANS AND TISSUES. MECHANISMS OF SUSCEPTIBILITY INCLUDE EPI-GENETIC AND POST-TRANSCRIPTIONAL EFFECTS THAT REGULATE TRANSMISSION AND EXPRESSION OF THE INHERITED GENES. THE HLA COMPLEX, CONSTITUTES THE MOST RELEVANT REGION CONTRIBUTING 50% OF THE INHERITED RISK FOR T1D. AN ADDITIONAL 17 GENES WITH VARIABLE BUT SMALL EFFECTS HAVE BEEN DESCRIBED. IN NON-CAUCASIANS, THE PRESENCE OF E-DRBETA1-74 AND/OR D-DRBETA1-57 ARE RELEVANT IN PREDISPOSITION. THE "DIABETOGENIC HAPLOTYPES" IN MEXICANS WERE DRB1*0301-DQA1*0501-DQB1*0201 (OR = 21.4); DRB1*0405-DQA1-*0301-DQB1*0302 (OR = 44.5) AND THE SAME DQA1/DQB1 WITH DRB1*0404/*0401 CONFERRING LOWER RISK, INCREASING (OR = 61.3) WITH AN EARLY AGE AT ONSET AND A HETEROZYGOTE DR3/DR4 GENOTYPE. IN MOST POPULATIONS, THE ABSENCE OF D-57 AND THE PRESENCE OF R-52 ARE IMPORTANT TO THE SUSCEPTIBILITY, BUT IN HISPANICS, ALL DR4S (INCLUDING THE PROTECTIVE DRB1*0403/*0407/*0411) ARE IN LINKAGE DISEQUILIBRIUM WITH DQA1/DQB1 SUSCEPTIBILITY ALLELES. THUS, SUSCEPTIBILITY ALLELES IN LATIN AMERICAN MESTIZOS ARE OF MEDITERRANEAN ANCESTRY WHEREAS PROTECTIVE ALLELES ARE OF AMERINDIAN ORIGIN. IN THIS REVIEW, WE DISCUSS THE COMPLEXITY OF T1D AND SOME ASPECTS OF PREVENTION/INTERVENTION BASED ON IMMUNOGENETICS.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
3 3074  21 GENOME-WIDE DNA METHYLOME AND TRANSCRIPTOME CHANGES INDUCED BY INORGANIC NANOPARTICLES IN HUMAN KIDNEY CELLS AFTER CHRONIC EXPOSURE. THE UNIQUE PHYSICOCHEMICAL PROPERTIES MAKE INORGANIC NANOPARTICLES (INPS) AN EXCITING TOOL IN DIAGNOSIS AND DISEASE MANAGEMENT. HOWEVER, AS INPS ARE RELATIVELY DIFFICULT TO FULLY DEGRADE AND EXCRETE, THEIR UNINTENDED ACCUMULATION IN THE TISSUE MIGHT RESULT IN ADVERSE HEALTH EFFECTS. HEREIN, WE PROVIDE A METHYLOME-TRANSCRIPTOME FRAMEWORK FOR CHRONIC EFFECTS OF INPS, COMMONLY USED IN BIOMEDICAL APPLICATIONS, IN HUMAN KIDNEY TH-1 CELLS. RENAL CLEARANCE IS ONE OF THE MOST IMPORTANT ROUTES OF NANOPARTICLE EXCRETION; THEREFORE, A DETAILED EVALUATION OF NANOPARTICLE-MEDIATED NEPHROTOXICITY IS AN IMPORTANT TASK. INTEGRATED ANALYSIS OF METHYLOME AND TRANSCRIPTOME CHANGES INDUCED BY INPS (PEG-AUNPS, FE(3)O(4)NPS, SIO(2)NPS, AND TIO(2)NPS) REVEALED SIGNIFICANTLY DEREGULATED GENES WITH FUNCTIONAL CLASSIFICATION IN IMMUNE RESPONSE, DNA DAMAGE, AND CANCER-RELATED PATHWAYS. ALTHOUGH MOST DEREGULATED GENES WERE UNIQUE TO INDIVIDUAL INPS, A RELATIVELY HIGH PROPORTION OF THEM ENCODED THE TRANSCRIPTION FACTORS. INTERESTINGLY, FOS HYPERMETHYLATION INVERSELY CORRELATING WITH GENE EXPRESSION WAS ASSOCIATED WITH ALL INPS EXPOSURES. OUR STUDY EMPHASIZES THE NEED FOR A MORE COMPREHENSIVE INVESTIGATION OF INPS' BIOLOGICAL SAFETY, ESPECIALLY AFTER CHRONIC EXPOSURE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
4 6351  26 THE ROLE OF EPIGENOMICS IN MAPPING POTENTIAL PRECURSORS FOR FOOT AND ANKLE TENDINOPATHY: A SYSTEMATIC REVIEW. TENDINOPATHY OF THE FOOT AND ANKLE IS A COMMON CLINICAL PROBLEM FOR WHICH THE EXACT ETIOLOGY IS POORLY UNDERSTOOD. THE FIELD OF EPIGENETICS HAS BEEN A RECENT FOCUS OF THIS INVESTIGATION. THE PURPOSE OF THIS ARTICLE WAS TO REVIEW THE GENOMIC ADVANCES IN FOOT AND ANKLE TENDINOPATHY THAT COULD POTENTIALLY BE USED TO STRATIFY DISEASE RISK AND CREATE PREVENTATIVE OR THERAPEUTIC AGENTS. A MULTI-DATABASE SEARCH OF PUBMED, COCHRANE, GOOGLE SCHOLAR, AND CLINICALTRIALS.GOV FROM JANUARY 1, 2000 TO JULY 1, 2022 WAS PERFORMED. A TOTAL OF 18 ARTICLES MET INCLUSION AND EXCLUSION CRITERIA FOR THIS REVIEW. THE MAJORITY OF SUCH RESEARCH UTILIZED CASE-CONTROL CANDIDATE GENE ASSOCIATION TO IDENTIFY DIFFERENT GENETIC RISK FACTORS ASSOCIATED WITH CHRONIC TENDINOPATHY. POLYMORPHISMS IN COLLAGEN GENES COL5A1, COL27A1, AND COL1A1 WERE NOTED AT A SIGNIFICANTLY HIGHER FREQUENCY IN ACHILLES TENDINOPATHY VERSUS CONTROL GROUPS. OTHER ALLELIC VARIATIONS THAT WERE OBSERVED AT AN INCREASED INCIDENCE IN ACHILLES TENDINOPATHY WERE TNC AND CASP8. THE EXTRACELLULAR MATRIX (ECM) DEMONSTRATED MACROSCOPIC CHANGES IN ACHILLES TENDINOPATHY, INCLUDING AN INCREASE IN AGGRECAN AND BIGLYCAN MRNA EXPRESSION, AND INCREASED EXPRESSION OF MULTIPLE MATRIX METALLOPROTEINASES. CYTOKINE EXPRESSION WAS ALSO INFLUENCED IN PATHOLOGY AND ABERRANTLY DEMONSTRATED DYNAMIC RESPONSE TO MECHANICAL LOAD. THE PATHOLOGIC ACCUMULATION OF ECM PROTEINS AND CYTOKINE EXPRESSION ALTERS THE ADAPTIVE RESPONSE NORMAL TENDON HAS TO PHYSIOLOGIC STRESS, FURTHER PROPAGATING THE RISK FOR TENDINOPATHY. BY IDENTIFYING AND UNDERSTANDING THE EPIGENETIC MEDIATORS THAT LEAD TO TENDINOPATHY, THERAPEUTIC AGENTS CAN BE DEVELOPED TO TARGET THE EXACT UNDERLYING ETIOLOGY AND MINIMIZE SIDE EFFECTS.LEVEL OF EVIDENCE: LEVEL IV: SYSTEMATIC REVIEW OF LEVEL II-IV STUDIES.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
5  820  30 CHARACTERIZATION OF A PORTUGUESE FAMILY WITH CHARCOT-MARIE-TOOTH DISEASE TYPE 1E DUE TO A NOVEL POINT MUTATION IN THE PMP22 GENE. INTRODUCTION: POINT MUTATIONS IN THE PERIPHERAL MYELIN PROTEIN 22 (PMP22) GENE COMPRISE LESS THAN 5% OF THE CHARCOT-MARIE-TOOTH (CMT) TYPE 1 CASES, AND INDIVIDUALIZE EITHER THE CMT 1E SUBTYPE, OR HEREDITARY NEUROPATHY WITH LIABILITY TO PRESSURE PALSY. THE PHENOTYPE OF CMT 1E PRESENTS WITH A SEVERE EARLY-ONSET POLYNEUROPATHY ASSOCIATED WITH DEAFNESS, ALTHOUGH THE CLINICAL SPECTRUM IS BROAD. CASE REPORT: WE DESCRIBE A NOVEL PMP22 GENE POINT MUTATION (C.84G>T;P.(TRP28CYS)) IN THREE PATIENTS OF A PORTUGUESE FAMILY WITH VARIABLE PHENOTYPES, RANGING FROM ASYMPTOMATIC TO MILD COMPLAINTS OF DISTAL LIMB NUMBNESS AND GAIT DIFFICULTIES, WITH THE AGE OF ONSET OF SYMPTOMS RANGING FROM MID-TWENTIES TO LATE-SIXTIES, AND NO ASSOCIATED DISABILITY. IN ALL AFFECTED PATIENTS, THERE WAS EVIDENCE OF DIFFUSE DEMYELINATING SENSORIMOTOR POLYNEUROPATHY. HEARING LOSS DOES NOT SEEM TO BE ASSOCIATED WITH THIS VARIANT, ALBEIT NEUROPATHIC PAIN WAS REPORTED. CONCLUSIONS: THESE FINDINGS SUGGEST THAT THIS PARTICULAR POINT MUTATION IN THE PMP22 GENE IS ASSOCIATED WITH A MILD PHENOTYPE, FURTHER EMPHASIZING THAT THERE ARE STILL UNKNOWN MECHANISMS (GENETIC AND/OR EPIGENETIC) THAT MAY PLAY A ROLE IN THE CLINICAL SPECTRUM OF CMT1E PATIENTS. NEXT GENERATION SEQUENCING PANELS INCLUDING COMMONLY MUTATED GENES IN CMT SHOULD BE CONSIDERED IN CMT1 CASES NEGATIVE FOR PMP22 GENE DUPLICATION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
6 6636  32 UNRAVELING A NEW PLAYER IN MULTIPLE SCLEROSIS PATHOGENESIS: THE RNA-BINDING PROTEIN HUR. BACKGROUND: ELAV-LIKE PROTEINS ARE A SMALL FAMILY OF RNA-BINDING PROTEINS THAT ARE FUNDAMENTAL PLAYERS IN POST-TRANSCRIPTIONAL MECHANISMS AND ARE INVOLVED IN THE PATHOGENESIS OF NEUROLOGIC AND PSYCHIATRIC DISORDERS. HUR, THE UBIQUITOUSLY EXPRESSED MEMBER OF THE FAMILY, IS ALSO IMPLICATED IN SUSTAINING INFLAMMATION AND INFLAMMATORY DISEASES, SUPPORTING THE PRODUCTION OF PRO-INFLAMMATORY CYTOKINES. INFLAMMATION PLAYS A CENTRAL ROLE IN MULTIPLE SCLEROSIS (MS), WHICH REPRESENTS THE MOST COMMON CAUSE OF PERMANENT PHYSICAL DISABILITY IN YOUNG ADULTS. MS IS A CHRONIC AUTOIMMUNE DISEASE AFFECTING THE CENTRAL NERVOUS SYSTEM, WITH A COMPLEX AETIOLOGY INVOLVING GENETIC, ENVIRONMENTAL AND EPIGENETIC FACTORS. NO DATA ARE AVAILABLE ON THE POTENTIAL ENTANGLEMENT OF HUR IN MS PATHOGENESIS IN PATIENTS. IN THE PRESENT WORK, WE AIMED AT EXPLORING HUR PROTEIN LEVELS IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) FROM MS PATIENTS, COMPARED TO HEALTHY CONTROLS. TO FURTHER ELUCIDATE THE POSSIBLE INVOLVEMENT OF HUR IN MS, WE ALSO INVESTIGATED THE RELATIONSHIP BETWEEN THIS SPECIFIC RNA-BINDING PROTEIN AND HSP70-2 PROTEIN, ALSO CONSIDERING THE HSP70-2 RS1061581 POLYMORPHISM, GIVEN THAT HSP70-2 MRNA HAS BEEN REPORTED AS A HUR TARGET AND THIS SPECIFIC POLYMORPHISM TO BE ASSOCIATED WITH MS RISK. METHODS: ALLELES AND GENOTYPES FOR HSP70-2 RS1061581 POLYMORPHISM WERE ASSESSED, BY USING A POLYMERASE CHAIN REACTION-RESTRICTION FRAGMENT LENGTH POLYMORPHISM, FOLLOWED BY DIGESTION WITH RESTRICTION ENZYME, IN MS PATIENTS AND HEALTHY CONTROLS. PBMCS FROM A SUBGROUP OF PATIENTS AND CONTROLS WERE USED TO EVALUATE HUR AND HSP70-2 PROTEIN CONTENT BY WESTERN BLOT. RESULTS: PBMCS FROM 52 MS PATIENTS HAD A LOWER HUR AND HIGHER HSP70-2 PROTEIN CONTENT COMPARED TO 43 HEALTHY CONTROLS. AN INCREASE OF 100 UNITS OF HUR SIGNIFICANTLY DECREASED THE RISK OF DEVELOPING MS BY 9.8% (OR: 0.902, 95% CI: 0.83-0.98), CONTROLLING FOR HSP70-2 PROTEIN EXPRESSION, HSP70-2 RS1061581 GENOTYPE, AGE AND SEX. MOREOVER, HOLDING HUR LEVELS, AN INCREASE OF 100 UNITS OF HSP70-2 PROTEIN SIGNIFICANTLY INCREASED THE MS RISK BY 18.1% (OR: 1.181, 95% CI: 1.03-1.36) AND THE GENETIC SUSCEPTIBILITY OF DEVELOPING MS FOR HSP70-2 RS1061581 GG CARRIERS IS CONFIRMED. OF INTEREST, MS PATIENTS WITH A MODERATE TO SEVERE FORM OF MS (MSSS >/= 3) SHOWED A TREND TOWARDS A REDUCTION OF HUR PROTEIN LEVELS COMPARED TO PATIENTS WITH MILD DISEASE SEVERITY (MSSS < 3). CONCLUSIONS: HUR PROTEIN LEVELS ARE REDUCED IN MS PATIENTS COMPARED TO HEALTHY SUBJECTS, AND THE PROTEIN AMOUNT MAY CONTINUE TO DECLINE WITH DISEASE PROGRESSION, SUGGESTING A PUTATIVE ROLE OF THIS RNA-BINDING PROTEIN. MOREOVER, OUR RESULTS SUGGEST THAT MS PATHOLOGY MAY HAVE DISRUPTED THE LINK BETWEEN HUR AND ITS TARGET TRANSCRIPT HSP70-2. IT WILL BE IMPORTANT TO FURTHER EXPLORE THE EXACT ROLE OF HUR IN MS, CONSIDERING THE COMPLEX INTERPLAY WITH OTHER RNA-BINDING FACTORS AND TARGET MRNAS.	2020	

7 6484  21 TOXICOLOGIC PROFILE OF ACRYLONITRILE. ACRYLONITRILE IS A MONOMER USED EXTENSIVELY AS A RAW MATERIAL IN THE MANUFACTURING OF ACRYLIC FIBERS, PLASTICS, SYNTHETIC RUBBERS, AND ACRYLAMIDE. IT HAS BEEN CLASSIFIED AS A PROBABLE HUMAN CARCINOGEN ACCORDING TO THE RESULTS OF NUMEROUS CHRONIC RAT BIOASSAYS. THE PRESENT REPORT SUMMARIZES THE TOXICITY DATA ON ACRYLONITRILE AND REVIEWS AVAILABLE DATA CONCERNING THE MECHANISM (GENETIC VERSUS EPIGENETIC) BY WHICH ACRYLONITRILE IS CARCINOGENIC IN RATS. FROM THE EVALUATION OF THE RELEVANT TOXICITY DATA, IT CAN BE CONCLUDED THAT ACRYLONITRILE IS INDEED CARCINOGENIC TO RATS AFTER EITHER ORAL OR INHALATIONAL EXPOSURE. HOWEVER, INFORMATION ON OTHER MAMMALIAN SPECIES IS LACKING, AND, MOREOVER, THE EXACT MECHANISM OF THE CARCINOGENIC PROCESS IS UNCLEAR. THEREFORE, IT IS RECOMMENDED TO CONDUCT AN ADDITIONAL LONG-TERM INHALATION CARCINOGENICITY STUDY WITH ACRYLONITRILE IN MICE, AS WELL AS STUDIES INTO THE MECHANISM BY WHICH ACRYLONITRILE INDUCES (BRAIN) TUMORS IN RATS (GENETIC VERSUS EPIGENETIC).	1998	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
8 6835  21 [INFLUENCE OF AGE OF PATIENTS WITH BRONCHOPULMONARY PATHOLOGY ON LOW-MOLECULAR DNA CONCENTRATION IN BLOOD PLASMA.]. THE AIM OF THE WORK WAS TO DETERMINE THE CONCENTRATION OF LOW-MOLECULAR-WEIGHT PLASMA DNA (LMDNA) IN PATIENTS WITH COPD AND CHRONIC NON-OBSTRUCTIVE BRONCHITIS (CNONB) OF TWO AGE GROUPS - 34-59 AND 60-80 YEARS. THE LEVELS OF LMDNA IN HEALTHY DONORS, PATIENTS WITH CNONB, HEALTHY RELATIVES OF PATIENTS WITH COPD DID NOT DIFFER, WHILE THE CONCENTRATION OF LMDNA IN PATIENTS WITH COPD WAS SIGNIFICANTLY LOWER. IN COPD PATIENTS AGED 34-59 YEARS, THE LEVEL OF LMDNA WAS REDUCED BY MORE THAN 7 TIMES, AND IN COPD PATIENTS WHO SURVIVED TO 60-80 YEARS, IT WAS 3 TIMES LOWER COMPARED TO THE VALUE OF THIS BIOCHEMICAL INDICATOR IN HEALTHY DONORS OF THE SAME AGE. THE REDUCTION OF LMDNA REFLECTED A REDUCED SYSTEMIC APOPTOTIC ACTIVITY IN THE BODY OF PATIENTS WITH COPD. A SIGNIFICANT DIFFERENCE IN THE CONCENTRATION OF LMDNA IN PATIENTS WITH COPD AND CNONB IN REMISSION CAN BE USED FOR DIFFERENTIAL DIAGNOSIS OF THE DEVELOPMENT OF THESE PATHOLOGICAL PROCESSES. AN INCREASE IN THE LOW LEVEL OF LMDNA IN COPD PATIENTS DURING AGING MAY INDICATE THE INVOLVEMENT OF EPIGENETIC MECHANISMS IN LIFE EXTENSION.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
9  645  23 BIRTH DEFECTS IN GAZA: PREVALENCE, TYPES, FAMILIARITY AND CORRELATION WITH ENVIRONMENTAL FACTORS. THIS IS THE FIRST REPORT OF REGISTRATION AT BIRTH, AND OF INCIDENCE OF MAJOR STRUCTURAL BIRTH DEFECTS (BD) OBTAINED IN GAZA AT AL SHIFA HOSPITAL, WHERE 28% OF TOTAL BIRTHS IN GAZA STRIP OCCUR. DOCTORS REGISTERED 4,027 DELIVERIES, WITH A PROTOCOL COMPREHENSIVE OF CLINICAL, DEMOGRAPHIC, KIN AND ENVIRONMENTAL QUESTIONS. PREVALENCE OF BD IS 14/1,000, WITHOUT ASSOCIATION WITH INTERMARRIAGE OR GENDER OF THE CHILD. PREVALENCE OF LATE MISCARRIAGES AND STILL BIRTHS ARE RESPECTIVELY 23.3/1,000 AND 7.4/1,000, AND OF PREMATURE BIRTHS 19.6/1,000. COUPLES WITH A BD CHILD HAVE ABOUT 10 TIMES HIGHER FREQUENCY OF RECURRENCE OF A BD IN THEIR PROGENY THAN THOSE WITH NORMAL CHILDREN, BUT NONE OF THEIR 694 SIBLINGS AND ONLY 10/1,000 OF THEIR 1,423 PROGENY HAD BD, SIMILAR TO THE FREQUENCY IN GENERAL POPULATION. THESE DATA SUGGEST OCCURRENCE OF NOVEL GENETIC AND EPIGENETIC EVENTS IN DETERMINATION OF BD. CHILDREN WITH BD WERE BORN WITH HIGHER FREQUENCY (P < 0 001) IN FAMILIES WHERE ONE OR BOTH PARENTS WERE UNDER "WHITE PHOSPHORUS" ATTACK, THAT IN THE GENERAL POPULATION. BOMBING OF THE FAMILY HOME AND REMOVAL OF THE RUBBLE WERE ALSO FREQUENTLY REPORTED BY COUPLES WITH BD OCCURRENCE. THESE DATA SUGGESTS A CAUSATIVE/FAVORING ROLE OF ACUTE EXPOSURE OF PARENTS TO THE WEAPONS-ASSOCIATED CONTAMINANTS, AND/OR OF THEIR CHRONIC EXPOSURE FROM THEIR PERSISTENCE IN THE ENVIRONMENT ON THE EMBRYONIC DEVELOPMENT OF THEIR CHILDREN.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
10 1109  21 COMMERCIAL PROCESSED SOY-BASED FOOD PRODUCT CONTAINS GLYCATED AND GLYCOXIDATED LUNASIN PROTEOFORMS. NUTRACEUTICALS HAVE BEEN PROPOSED TO EXERT POSITIVE EFFECTS ON HUMAN HEALTH AND CONFER PROTECTION AGAINST MANY CHRONIC DISEASES. A MAJOR BIOACTIVE COMPONENT OF SOY-BASED FOODS IS LUNASIN PEPTIDE, WHICH HAS POTENTIAL TO EXERT A MAJOR IMPACT ON THE HEALTH OF HUMAN CONSUMERS WORLDWIDE, BUT THE BIOCHEMICAL FEATURES OF DIETARY LUNASIN STILL REMAIN POORLY CHARACTERIZED. IN THIS STUDY, LUNASIN WAS PURIFIED FROM A SOY-BASED FOOD PRODUCT VIA STRONG ANION EXCHANGE SOLID PHASE EXTRACTION AND THEN SUBJECTED TO TOP-DOWN MASS SPECTROMETRY ANALYSIS THAT REVEALED IN DETAIL THE MOLECULAR DIVERSITY OF LUNASIN IN PROCESSED SOYBEAN FOODS. WE DETECTED MULTIPLE GLYCATED PROTEOFORMS TOGETHER WITH POTENTIALLY TOXIC ADVANCED GLYCATION END PRODUCTS (AGES) DERIVED FROM LUNASIN. IN BOTH CASES, MODIFICATION SITES WERE LYS24 AND LYS29 LOCATED AT THE HELICAL REGION THAT SHOWS STRUCTURAL HOMOLOGY WITH A CONSERVED REGION OF CHROMATIN-BINDING PROTEINS. THE IDENTIFIED POST-TRANSLATIONAL MODIFICATIONS MAY HAVE AN IMPORTANT REPERCUSSION ON LUNASIN EPIGENETIC REGULATORY CAPACITY. TAKING TOGETHER, OUR RESULTS DEMONSTRATE THE IMPORTANCE OF PROPER CHEMICAL CHARACTERIZATION OF COMMERCIAL PROCESSED FOOD PRODUCTS TO ASSESS THEIR IMPACT ON CONSUMER'S HEALTH AND RISK OF CHRONIC DISEASES.	2016

12 5353  24 RE-EVALUATION OF POLIHEXANIDE USE IN WOUND ANTISEPSIS IN ORDER TO CLARIFY AMBIGUITIES OF TWO ANIMAL STUDIES. OBJECTIVE: DUE TO CLASSIFICATION OF THE AGENT POLIHEXANIDE (PHMB) IN CATEGORY 2 'MAY CAUSE CANCER' BY THE COMMITTEE FOR RISK ASSESSMENT OF THE EUROPEAN CHEMICALS AGENCY IN 2011, THE USERS OF WOUND ANTISEPTICS MAY BE HIGHLY CONFUSED. IN 2017, THIS STATEMENT WAS UPDATED, DEFINING PHMB UP TO 0.1% AS A PRESERVATIVE SAFE IN ALL COSMETIC PRODUCTS. IN THE INTEREST OF PATIENT SAFETY, A SCIENTIFIC CLARIFICATION OF THE POTENTIAL CARCINOGENICITY OF PHMB IS NECESSARY. METHODS: A MULTIDISCIPLINARY TEAM (MDT) OF MICROBIOLOGISTS, SURGEONS, DERMATOLOGISTS AND BIOCHEMISTS CONDUCTED A BENEFIT-RISK ASSESSMENT TO CLARIFY THE HAZARD OF ANTISEPTIC USE OF PHMB. RESULTS: IN TWO ANIMAL STUDIES, FROM WHICH THE ASSESSMENT OF A CARCINOGENIC RISK WAS DERIVED, PHMB WAS ADMINISTERED ORALLY OVER TWO YEARS IN EXTREMELY HIGH CONCENTRATIONS FAR ABOVE THE NO(A)EL (NO-OBSERVED-(ADVERSE-) EFFECT LEVEL) IN RATS AND MICE. FEEDING IN THE NO(A)EL RANGE RESULTED IN NO ABNORMAL EFFECTS. IN ONE MALE IN THE HIGHEST DOSE GROUP OF 4000PPM PHMB, AN ADENOCARCINOMA WAS FOUND, WHICH THE AUTHOR ATTRIBUTED TO CHRONIC INFLAMMATION OF THE COLON WITH SYSTEMIC ATYPICAL EXPOSURE. THE INCREASING INCIDENCE OF HEMANGIOSARCOMAS HIGHLY PROBABLY RESULTED FROM INCREASED ENDOTHELIAL PROLIFERATION, TRIGGERED BY THE EXCEEDINGLY HIGH DOSAGE FED, BECAUSE PHMB IS NOT GENOTOXIC AND THERE IS NO EVIDENCE FOR EPIGENETIC EFFECTS. DISCUSSION: IT IS WELL KNOWN THAT PHMB IS NOT ABSORBED WHEN APPLIED TOPICALLY. CONSIDERING THE ABSENCE OF GENOTOXICITY AND EPIGENETIC EFFECTS TOGETHER WITH THE INTERPRETATION OF THE ANIMAL STUDIES, IT IS THE CONSENSUS OF THE MULTIDISCIPLINARY EXPERTS THAT A CARCINOGENIC RISK FROM PHMB-USE FOR WOUND ANTISEPSIS CAN BE RULED OUT. CONCLUSION: ON THIS BASIS AND CONSIDERING THEIR EFFECTIVENESS, TOLERABILITY AND CLINICAL EVIDENCE, THE INDICATIONS FOR PHMB BASED WOUND ANTISEPTICS ARE JUSTIFIED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
13 5356  19 REAC-INDUCED ENDOGENOUS BIOELECTRIC CURRENTS IN THE TREATMENT OF VENOUS ULCERS: A THREE-ARM RANDOMIZED CONTROLLED PROSPECTIVE STUDY. INTRODUCTION: ENDOGENOUS BIOELECTRIC FIELDS (EBFS) PLAY A FUNDAMENTAL ROLE IN PROMOTING REPAIR AND REGENERATION PROCESSES, INCLUDING IN LEG VENOUS ULCERS (LVUS). UNFORTUNATELY, THE MECHANISM UNDERLYING THE PRODUCTION OF EBFS IS EASILY ALTERED BY INFECTIOUS, TRAUMATIC, AND EPIGENETIC FACTORS. THIS ALTERATION IS ONE OF THE DETERMINING FACTORS FOR THE CHRONICITY OF LVUS. THIS STUDY INVESTIGATES HOW RADIOELECTRIC ASYMMETRIC CONVEYER (REAC) TECHNOLOGY TREATMENTS, SPECIFICALLY DESIGNED TO OPTIMIZE EBFS, AND IN PARTICULAR TISSUE OPTIMIZATION-REPARATIVE (TO-RPR) TREATMENT, CAN IMPROVE THE RESULTS OF STANDARD DRESSING WITH AND WITHOUT ELASTIC COMPRESSION IN LVU PATIENTS. METHODS: A TOTAL OF 30 PATIENTS WERE ENROLLED (12 MALES AND 18 FEMALES) AND RANDOMIZED INTO THREE GROUPS. ALL PATIENTS COMPLETED THE STUDY. GROUP A WAS TREATED WITH STANDARD DRESSING, ELASTIC COMPRESSION, AND REAC TO-RPR TREATMENT; GROUP B WAS TREATED WITH STANDARD DRESSING AND REAC TO-RPR TREATMENT; AND GROUP C WAS TREATED WITH STANDARD DRESSING AND ELASTIC COMPRESSION. RESULTS: THE RESULTS SHOW THAT THE COMBINATION OF REAC TREATMENT AND STANDARD DRESSING ASSOCIATED WITH ELASTIC COMPRESSION HAS THE GREATEST THERAPEUTIC EFFICACY IN PROMOTING THE HEALING PROCESS FOR ULCERS, REDUCING PERCEIVED PAIN, AND IMPROVING THE QUALITY OF LIFE OF THE PATIENTS TREATED. CONCLUSIONS: FURTHER STUDIES WILL BE USEFUL TO INVESTIGATE THESE PROSPECTIVE RESULTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
14 2761  19 EXPRESSION OF TESTIS-SPECIFIC GENES, TEX101 AND ODF4, IN CHRONIC MYELOID LEUKEMIA AND EVALUATION OF TEX101 IMMUNOGENICITY. BACKGROUND AND OBJECTIVES: CANCER-TESTIS (CT) ANTIGENS ARE A GROUP OF ANTIGENS WITH A RESTRICTED EXPRESSION IN NORMAL TISSUES, EXCEPT TESTIS, AND THEY HAVE ABERRANT EXPRESSION IN DIFFERENT TUMORS. THIS PATTERN OF EXPRESSION HAS MADE THEM PROMISING TARGETS FOR IMMUNOTHERAPY AND CANCER DETECTION. OUR AIM WAS TO FIND NEW MEMBERS OF THIS GROUP THAT MIGHT BE USEFUL AS MARKERS IN THE DETECTION OF CANCER AND IMMUNOTHERAPY. DESIGN AND SETTING: A DESCRIPTIVE STUDY CONDUCTED IN REFERRAL CENTERS OF TEHRAN UNIVERSITY OF MEDICAL SCIENCE FROM JANUARY 2008 TO JANUARY 2009. PATIENTS AND METHODS: WE ANALYZED THE EXPRESSION OF TWO TESTIS-SPECIFIC GENES NAMED ODF4 (OUTER DENSE FIBER OF SPERM TAILS 4) AND TEX101 (TESTIS EXPRESSED 101) IN 20 CHRONIC MYELOID LEUKEMIA (CML) AND 20 NORMAL SAMPLES BY REVERSE TRANSCRIPTION-POLYMERASE CHAIN REACTION AND SEQUENCING. IMMUNOGENICITY OF TEX101 WAS EVALUATED BY MEANS OF ENZYME-LINKED IMMUNOSORBENT ASSAY. RESULTS: THESE TWO GENES WERE EXPRESSED IN 30% OF CML PATIENTS BUT NOT IN ANY OF THE HEALTHY DONORS. HUMORAL RESPONSE AGAINST TEX101 WAS NOT DETECTED IN ANY SAMPLES. CONCLUSIONS: TEX101 AND ODF4 ARE CT GENES USEFUL FOR DETECTION OF CML. UNLIKE MANY CT GENES, OVEREXPRESSION OF TEX101 WAS NOT SHOWN TO INDUCE IMMUNOLOGIC RESPONSES IN THESE SAMPLES. ACCORDING TO THE PREVIOUS STUDIES, OVEREXPRESSION OF TEX101 LEADS TO SUPPRESSION OF CANCER INVASION AND METASTASIS; THUS, THE INDUCTION OF THE EXPRESSION OF TEX101 IN CANCER BY EPIGENETIC MECHANISMS MAY BE A TREATMENT STRATEGY.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
15 3130  30 GLAST BUT NOT LEAST--DISTRIBUTION, FUNCTION, GENETICS AND EPIGENETICS OF L-GLUTAMATE TRANSPORT IN BRAIN--FOCUS ON GLAST/EAAT1. SYNAPTICALLY RELEASED L-GLUTAMATE, THE MOST IMPORTANT EXCITATORY NEUROTRANSMITTER IN THE CNS, IS REMOVED FROM EXTRACELLULAR SPACE BY FAST AND EFFICIENT TRANSPORT MEDIATED BY SEVERAL TRANSPORTERS; THE MOST ABUNDANT ONES ARE EAAT1/GLAST AND EAAT2/GLT1. THE REVIEW FIRST SUMMARIZES THEIR LOCATION, FUNCTIONS AND BASIC CHARACTERISTICS. WE THEN LOOK AT GENETICS AND EPIGENETICS OF EAAT1/GLAST AND EAAT2/GLT1 AND PERFORM IN SILICO ANALYSES OF THEIR PROMOTER REGIONS. THERE IS ONE CPG ISLAND IN SLC1A2 (EAAT2/GLT1) GENE AND NONE IN SLC1A3 (EAAT1/GLAST) SUGGESTING THAT DNA METHYLATION IS NOT THE MOST IMPORTANT EPIGENETIC MECHANISM REGULATING EAAT1/GLAST LEVELS IN BRAIN. THERE ARE TARGETS FOR SPECIFIC MIRNA IN SLC1A2 (EAAT2/GLT1) GENE. WE ALSO NOTE THAT WHILE DEFECTS IN EAAT2/GLT1 HAVE BEEN ASSOCIATED WITH VARIOUS PATHOLOGICAL STATES INCLUDING CHRONIC NEURODEGENERATIVE DISEASES, VERY LITTLE IS KNOWN ON POSSIBLE CONTRIBUTIONS OF DEFECTIVE OR DYSFUNCTIONAL EAAT1/GLAST TO ANY SPECIFIC BRAIN DISEASE. FINALLY, WE REVIEW EVIDENCE OF EAAT1/GLAST INVOLVEMENT IN MECHANISMS OF BRAIN RESPONSE TO ALCOHOLISM AND PRESENT SOME PRELIMINARY DATA SHOWING THAT ETHANOL, AT CONCENTRATIONS WHICH MAY BE REACHED FOLLOWING HEAVY DRINKING, CAN HAVE AN EFFECT ON THE DISTRIBUTION OF EAAT1/GLAST IN CULTURED ASTROCYTES; THE EFFECT IS BLOCKED BY BACLOFEN, A GABA-B RECEPTOR AGONIST AND A DRUG POTENTIALLY USEFUL IN THE TREATMENT OF ALCOHOLISM. WE ARGUE THAT MORE RESEARCH EFFORT SHOULD BE FOCUSED ON EAAT1/GLAST, PARTICULARLY IN RELATION TO ALCOHOLISM AND DRUG ADDICTION.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
16 6358  34 THE ROLE OF IL?16 GENE POLYMORPHISMS IN ENDOMETRIOSIS. ENDOMETRIOSIS IS ONE OF THE MOST COMMON GYNECOLOGICAL DISEASES AFFECTING UP TO 10% OF THE FEMALE POPULATION OF CHILDBEARING AGE AND A MAJOR CAUSE OF PAIN AND INFERTILITY. IT IS INFLUENCED BY MULTIPLE GENETIC, EPIGENETIC AND ENVIRONMENTAL FACTORS. INTERLEUKIN?16 (IL?16) IS A PROINFLAMMATORY CYTOKINE PLAYING A PIVOTAL ROLE IN MANY INFLAMMATORY AND AUTOIMMUNE DISEASES AS WELL AS IN THE PATHOGENESIS OF ENDOMETRIOSIS. THE AIM OF THE PRESENT STUDY WAS TO EVALUATE THE ASSOCIATION OF TWO IL?16 GENE SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS), RS4072111 AND RS11556218, WITH THE RISK OF ENDOMETRIOSIS IN WOMEN FROM GREECE AS WELL AS TO GAIN INSIGHT ABOUT THE STRUCTURAL CONSEQUENCES OF THESE TWO EXONIC SNPS REGARDING DEVELOPMENT OF THE DISEASE. A TOTAL OF 159 WOMEN WITH ENDOMETRIOSIS (STAGES I?IV) HOSPITALIZED FOR ENDOMETRIOSIS, DIAGNOSED BY LAPAROSCOPIC INTERVENTION AND HISTOLOGICALLY CONFIRMED, AND 146 NORMAL CONTROLS WERE RECRUITED AND GENOTYPED. SUBJECTS WERE GENOTYPED USING A POLYMERASE CHAIN REACTION RESTRICTION FRAGMENT LENGTH POLYMORPHISM (PCR?RFLP) STRATEGY. A SIGNIFICANT ASSOCIATION WAS DETECTED REGARDING THE GG AND GT GENOTYPE AS WELL AS 'G' ALLELE OF RS11556218 IN PATIENTS WITH ENDOMETRIOSIS. THE RS4072111 SNP OF THE IL?16 GENE WAS NOT FOUND TO BE ASSOCIATED WITH AN INCREASED SUSCEPTIBILITY TO ENDOMETRIOSIS EITHER FOR ALL PATIENTS (STAGES I?IV) OR FOR STAGE III AND IV OF THE DISEASE ONLY. OUR RESULTS DEMONSTRATED THAT RS11556218 IS ASSOCIATED WITH ENDOMETRIOSIS IN GREEK WOMEN, PROBABLY BY RESULTING IN THE ABERRANT EXPRESSION OF IL?16, AS SUGGESTED BY THE BIOINFORMATICS ANALYSIS CONDUCTED ON THE SNP?DERIVED PROTEIN SEQUENCES, WHICH INDICATED A POSSIBLE ASSOCIATION BETWEEN MUTATION AND FUNCTIONAL MODIFICATION OF PRO?IL?16.	2018

ATYPICALLY, THERE WERE SIGNIFICANT DIFFERENCES BETWEEN TWINS IN PHENOTYPE SEVERITY, SUGGESTIVE OF EPIGENETIC DIFFERENCES AND/OR INVOLVEMENT OF ENVIRONMENTAL FACTORS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
18 5511  25 RIBONUCLEASES IN TUMOR GROWTH. THIS REVIEW SUMMARIZES DATA ON AMBIGUOUS BIOLOGICAL FUNCTIONS OF RIBONUCLEASES (RNASES) AT TUMOR GROWTH. IN SOME CASES THE RAISED LEVEL OF ENZYME ACTIVITY IN BIOLOGICAL FLUIDS CAN BE REGARDED AS AN ADDITIONAL MARKER OF MALIGNANT GROWTH (PANCREAS CANCER, CHRONIC MYELOID LEUKEMIA, ETC.). AT THE SAME TIME THE ACTIVITY OF RNASES IS OFTEN LOWERED IN TUMOR TISSUE. HIGH SUBSTRATE SPECIFICITY OF PARTICULAR RNASES PROVIDES METABOLIC BALANCE BETWEEN VARIOUS KINDS OF RNAS WITH VARIOUS HALF-TIME EXCHANGE TURN. RNASES ARE THE IMPORTANT FACTORS OF EPIGENETIC REGULATION OF GENE ACTIVITY IN CELLS. THE ACTIVITY OF RNASES IS ADJUSTABLE BY INHIBITORS AND OTHER FACTORS, AND DEFINES TIME OF EXISTENCE OF DIFFERENT KINDS OF RNAS. RNASES (THE MODIFIED VARIANTS OF RNASE A, RNASES OF SEMEN FLUID OF THE CATTLE, RNASE OF AMPHIBIA OOCYTES) CAN BE USED AS ANTI-TUMOR THERAPEUTIC AGENTS. ON THE OTHER HAND, SOME INHIBITORS OF RNASES OF NATURAL OR SYNTHETIC ORIGIN WERE DEMONSTRATED TO BE PERSPECTIVE DRUGS THAT INHIBIT TUMOR GROWTH.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
19 1187  28 COPD GWAS VARIANT AT 19Q13.2 IN RELATION WITH DNA METHYLATION AND GENE EXPRESSION. CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) IS AMONG THE MAJOR HEALTH BURDENS IN ADULTS. WHILE CIGARETTE SMOKING IS THE LEADING RISK FACTOR, A GROWING NUMBER OF GENETIC VARIATIONS HAVE BEEN DISCOVERED TO INFLUENCE DISEASE SUSCEPTIBILITY. EPIGENETIC MODIFICATIONS MAY MEDIATE THE RESPONSE OF THE GENOME TO SMOKING AND REGULATE GENE EXPRESSION. CHROMOSOME 19Q13.2 REGION IS ASSOCIATED WITH BOTH SMOKING AND COPD, YET ITS FUNCTIONAL ROLE IS UNCLEAR. OUR STUDY AIMED TO DETERMINE WHETHER RS7937 (RAB4B, EGLN2), A TOP GENETIC VARIANT IN 19Q13.2 REGION IDENTIFIED IN GENOME-WIDE ASSOCIATION STUDIES OF COPD, IS ASSOCIATED WITH DIFFERENTIAL DNA METHYLATION IN BLOOD (N = 1490) AND GENE EXPRESSION IN BLOOD (N = 721) AND LUNGS (N = 1087). WE COMBINED GENETIC AND EPIGENETIC DATA FROM THE ROTTERDAM STUDY (RS) TO PERFORM THE EPIGENOME-WIDE ASSOCIATION ANALYSIS OF RS7937. FURTHER, WE USED GENETIC AND TRANSCRIPTOMIC DATA FROM BLOOD (RS) AND FROM LUNG TISSUE (LUNG EXPRESSION QUANTITATIVE TRAIT LOCI MAPPING STUDY), TO PERFORM THE TRANSCRIPTOME-WIDE ASSOCIATION STUDY OF RS7937. RS7937 WAS SIGNIFICANTLY (FDR < 0.05) AND CONSISTENTLY ASSOCIATED WITH DIFFERENTIAL DNA METHYLATION IN BLOOD AT 4 CPG SITES IN CIS, INDEPENDENT OF SMOKING. ONE METHYLATION SITE (CG11298343-EGLN2) WAS ALSO ASSOCIATED WITH COPD (P = 0.001). ADDITIONALLY, RS7937 WAS ASSOCIATED WITH GENE EXPRESSION LEVELS IN BLOOD IN CIS (EGLN2), 42% MEDIATED THROUGH CG11298343, AND IN LUNG TISSUE, IN CIS AND TRANS (NUMBL, EGLN2, DNMT3A, LOC101929709 AND PAK2). OUR RESULTS SUGGEST THAT CHANGES OF DNA METHYLATION AND GENE EXPRESSION MAY BE INTERMEDIATE STEPS BETWEEN GENETIC VARIANTS AND COPD, BUT FURTHER CAUSAL STUDIES IN LUNG TISSUE SHOULD CONFIRM THIS HYPOTHESIS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
20 4492  21 MONOZYGOTIC TWINS DISCORDANT FOR ROHHAD PHENOTYPE. RAPID-ONSET OBESITY WITH HYPOTHALAMIC DYSFUNCTION, HYPOVENTILATION, AND AUTONOMIC DYSREGULATION (ROHHAD) FALLS WITHIN A GROUP OF PEDIATRIC DISORDERS WITH BOTH RESPIRATORY CONTROL AND AUTONOMIC NERVOUS SYSTEM DYSREGULATION. CHILDREN WITH ROHHAD TYPICALLY PRESENT AFTER 1.5 YEARS OF AGE WITH RAPID WEIGHT GAIN AS THE INITIAL SIGN. SUBSEQUENTLY, THEY DEVELOP ALVEOLAR HYPOVENTILATION, AUTONOMIC NERVOUS SYSTEM DYSREGULATION, AND, IF UNTREATED, CARDIORESPIRATORY ARREST. TO OUR KNOWLEDGE, THIS IS THE FIRST REPORT OF DISCORDANT PRESENTATION OF ROHHAD IN MONOZYGOTIC TWINS. TWIN GIRLS, BORN AT TERM, HAD CONCORDANT GROWTH AND DEVELOPMENT UNTIL 8 YEARS OF AGE. FROM 8 TO 12 YEARS OF AGE, THE AFFECTED TWIN DEVELOPED FEATURES CHARACTERISTIC OF ROHHAD INCLUDING OBESITY, ALVEOLAR HYPOVENTILATION, SCOLIOSIS, HYPOTHALAMIC DYSFUNCTION (CENTRAL DIABETES INSIPIDUS, HYPOTHYROIDISM, PREMATURE PUBARCHE, AND GROWTH HORMONE DEFICIENCY), RIGHT PARASPINAL/THORACIC GANGLIONEUROBLASTOMA, SEIZURES, AND AUTONOMIC DYSREGULATION INCLUDING ALTERED PAIN PERCEPTION, LARGE AND SLUGGISHLY REACTIVE PUPILS, HYPOTHERMIA, AND PROFOUND BRADYCARDIA THAT REQUIRED A CARDIAC PACEMAKER. RESULTS OF GENETIC TESTING FOR PHOX2B (CONGENITAL CENTRAL HYPOVENTILATION SYNDROME DISEASE-DEFINING GENE) MUTATIONS WERE NEGATIVE. WITH EARLY RECOGNITION AND CONSERVATIVE MANAGEMENT, THE AFFECTED TWIN HAD EXCELLENT NEUROCOGNITIVE OUTCOME THAT MATCHED THAT OF THE UNAFFECTED TWIN. THE UNAFFECTED TWIN DEMONSTRATED RAPID WEIGHT GAIN LATER IN AGE BUT NOT DEVELOPMENT OF SIGNS/SYMPTOMS CONSISTENT WITH ROHHAD. THIS DISCORDANT TWIN PAIR DEMONSTRATES KEY FEATURES OF ROHHAD INCLUDING THE IMPORTANCE OF EARLY RECOGNITION (ESPECIALLY HYPOVENTILATION), COMPLEXITY OF SIGNS/SYMPTOMS AND CLINICAL COURSE, AND IMPORTANCE OF INITIATING COMPREHENSIVE, MULTISPECIALTY CARE. THESE CASES CONFOUND THE HYPOTHESIS OF A MONOGENIC ETIOLOGY FOR ROHHAD AND INDICATE ALTERNATIVE ETIOLOGIES INCLUDING AUTOIMMUNE OR EPIGENETIC PHENOMENON OR A COMBINATION OF GENETIC PREDISPOSITION AND ACQUIRED PRECIPITANT.	2011
