dnajc3 mutation and diabetes - Absence of BiP Cochaperone DNAJC3 Causes diabetes kering seperti apa Diabetes Mellitus Expanding the phenotype of DNAJC3 mutations A case with Results DNAJC3 defect led to betacell dysfunction causing hyperinsulinemichypoglycemia around 2 years of age in both patients which evolved into diabetes with insulin deficiency in the second decade of life probably due to beta cell loss Endocrine phenotype involved severe earlyonset growth failure due to growth hormone deficiency and monogenic diabetes is suspected when there is a family history of diabetes with an autosomal dominant pattern of inheritance and onsetbefore 25 yearsold 16 Mutations in genesthat regulate bcell function have been identified as the cause of monogenic diabetes 1721 Rare mutations such as the DNAJC3 mutation which is Absence of BiP Cochaperone DNAJC3 Causes Diabetes Mellitus Homozygous DNAJC3 mutations have been reported to cause nonimmune juvenileonset diabetes neurodegeneration hearing loss short stature and hypothyroidism Case Description We report a case of homozygous DNAJC3 mutation in two siblings of a consanguineous family A 3yearold boy presented with short stature and a thyroid nodule DNAJC3 deficiency induces βcell mitochondrial apoptosis and Therefore we suggest DNAJC3 mutations should be included in the differential diagnosis when investigating suspected mitochondrial disease Our knowledge of the homozygous DNAJC3 mutation phenotypes is evolving This condition should be suspected in youth presenting with juvenileonset diabetes ataxia SNHL progressive neurodegeneration Frontiers Case Report Homozygous DNAJC3 Mutation Causes Homozygous DNAJC3 mutations have been reported to cause nonimmune juvenileonset diabetes neurodegeneration hearing loss short stature and hypothyroidism Case description We report a case of homozygous DNAJC3 mutation in two siblings of a consanguineous family A 3yearold boy presented with short stature and a thyroid nodule DNAJC3 deficiency induces βcell mitochondrial apoptosis and Monogenic and Syndromic Diabetes due to Endoplasmic Reticulum Therefore mutations in DNAJC3 lead to increased ER stress and apoptosis in βcells 93 A few pathogenic variants in DNAJC3 as well as deletions of DNAJC3 locus have been reported in patients with ACPHD Microcephaly Epilepsy and Diabetes Syndrome MEDS Case Report Homozygous DNAJC3 Mutation Causes Monogenic A Missense Mutation in PPP1R15B Causes a Syndrome Including Dnajc3 knockout causes gradual onset of hyperglycemia and glucosuria associated with increasing apoptosis of pancreatic β cells in mice thus mimicking disease processes in type 1 and latestage type 2 diabetes 6 Our findings demonstrate thatanalogous to the mouse modelhomozygous DNAJC3 lossoffunction mutations cause youngonset A lossoffunction mutation leads to diabetes mellitus and multisystemic neurodegeneration Synofzik et al 2015 and in mice DNAJC3 knockout mice had a phenotype of partial loss of pancreatic Case Report Homozygous DNAJC3 Mutation Causes Monogenic Identification of this additional patient from a distant part of the originally described pedigree Synofzik et al 2014 confirms pathogenicity of DNAJC3 mutations Hypothyroidism is a newly identified feature in addition to the known phenotype diabetes with multisystemic neurodegeneration Introduction Monogenic diabetes results from a mutation in single gene predominantly inherited alat untuk cek diabetes and typically affects the young DNAJC3 acts in attenuating endoplasmic reticulum stress and is found in abundance in pancreatic tissue Clinical Case We report a homozygous DNAJC3 mutation in two siblings of a consanguineous Saudi family A 3year DNAJC3 deficiency induces βcell mitochondrial apoptosis and Unmitigated ER stress contributes to βcell demise in several other monogenic forms of diabetes Mutations in the insulin gene that disrupt proinsulin folding cause severe βcell ER stress and neonatal diabetes The loss of the ER cochaperone p58 IPK due to DNAJC3 mutations leads to a syndrome with youngonset diabetes Clinical and genetic characteristics of two families with novel DNAJC3 mutations Diabetic probands P1 and P2 are shown in black symbols Diabetes status of relatives in family 1 was established Case Report Homozygous DNAJC3 Mutation Causes Monogenic Reduced DNAJC3 Expression Affects Protein Translocation Novel insights into diabetes mellitus due to DNAJC3defect PDF Absence of BiP Cochaperone DNAJC3 causes diabetes Objective DNAJC3 also known as P58IPK is an Hsp40 family member that interacts with and inhibits PKRlike ERlocalized eIF2α kinase PERK Dnajc3 deficiency in mice causes pancreatic βcell loss and diabetes Lossoffunction mutations in DNAJC3 cause earlyonset diabetes and multisystemic neurodegeneration Mutations leading to loss of the ER protein DNAJC3which serves to attenuate late phases of ER stress 5 have been shown to lead to pancreatic β cell failure and diabetes in mice 6 However it is still unknown whether mutations in DNAJC3 MIM 601184 RefSeq accession number NM0062604 also cause disease in humans DNAJC3 also known as P58 IPK is an Hsp40 family member that interacts with and inhibits PKRlike ERlocalized eIF2α kinase PERK Dnajc3 deficiency in mice causes pancreatic βcell loss and diabetes Lossoffunction mutations in DNAJC3 cause earlyonset diabetes and multisystemic neurodegeneration The aim of our study was to investigate Role of the DNAJHSP40 family in the pathogenesis of insulin Furthermore DNAJC3 lossoffunction mutations have been identified in patients that were diagnosed with earlyonset diabetes mellitus and suffered from multisystemic neurodegeneration including ataxia sensorimotor neuropathy and sensorineural hearing loss which appear to be systematic features of the DNAJC3diseased phenotype 505152 Case Report and Literature Review Homozygous DNAJC3 Mutation Congenital Hyperinsulinism in Humans and Insulin Secretory The BiP cochaperone DNAJC3 protects cells during ER stress In mice the deficiency of DNAJC3 leads to betacell apoptosis and the gradual onset of hyperglycemia In humans biallelic DNAJC3 variants cause a multisystem disease including earlyonset diabetes mellitus Recently hyperinsulinemic hypoglycemia HH has been recognized as part of this syndrome This report presents a case study The findings that link downregulation of DNAJC3 with T2D in animal models have been reflected in humans with mutations in the DNAC3 locus A lossoffunction DNAJC3 mutation resulting from homozygous stop or deletion has been reported in 5 patients from 2 Turkish families with a monogenic recessive form of diabetes bubur ayam amankah untuk diabetes Synofzik et al 2014
