Autosomal Recessive Nonsyndromic Hearing Loss: A Case Report with a Mutation in TRIOBP Gene
نویسندگان
چکیده
Hearing loss (HL) is the most common sensory defect. Various genetic as well as environmental factors have been shown to contribute in it. More than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (ARNSHL). Here, we report a 6-year old female patient with bilateral pre-lingual HL in whom a mutation has been identified in TRIOBP gene (c.6362C>T, S2121L). In silico analysis has shown that this variant is possibly pathogenic. Although several mutations have been detected in this gene in various populations, this is the first report identifying TRIOBP mutation in Iranian population. Consequently, the results of the present study may be of importance in genetic counseling.

متن کاملغربالگری ناشنوایان غیرسندرمی جسمی مغلوب برای جایگاه کروموزومی ناشنوایی غیرسندرمی با وراثت مغلوب نوع I(DFNB1) در استان‌های آذربایجان شرقی و غربی
Background & Aim: Hereditary hearing loss(HHL) affects one in 1000-2000 newborns and more than 50% of these cases have a genetic base. About 70% of HHL are nonsyndromic with autosomal recessive forms accounting for 85% of the genetic load. Different genes have been reported to be involved, but mutations in GJB2 gene at DFNB1 locus have been established as the basis of autosomal recessive no...
متن کاملScreening of DFNB3 in Iranian families with autosomal recessive non-syndromic hearing loss reveals a novel pathogenic mutation in the MyTh4 domain of the MYO15A gene in a linked family
Objective(s): Non-syndromic sensorineural hearing loss (NSHL) is a common disorder affecting approximately 1 in 500 newborns. This type of hearing loss is extremely heterogeneous and includes over 100 loci. Mutations in the GJB2 gene have been implicated in about half of autosomal recessive NSHL (ARNSHL) cases, making this the most common cause of ARNSHL. For the latter form of deafness, most f...
متن کاملTargeted Next-Generation Sequencing of a Deafness Gene Panel (MiamiOtoGenes) Analysis in Families Unsuitable for Linkage Analysis
Hearing loss (HL) is a common sensory disorder in humans with high genetic heterogeneity. To date, over 145 loci have been identified to cause nonsyndromic deafness. Furthermore, there are countless families unsuitable for the conventional linkage analysis. In the present study, we used a custom capture panel (MiamiOtoGenes) to target sequence 180 deafness-associated genes in 5 GJB2 negative de...

Background and Objective: TMC1 gene mutations are known as the most common causes of autosomal recessive non-syndromic hearing loss (ARNSHL) in different populations. According to large size of the TMC1 gene and the large number of identified mutations in this gene, application of polymorphic markers is suggested for carrier detection and prenatal diagnosis in families. In this study, informati...
