Evaluation of GJB2 and GJB6 Mutations in Patients Afflicted with Non-syndromic Hearing Loss
Background Non-syndromic hearing loss (NSHL) is assumed as one of the highly prevalent congenital defects in the world. In this regard, gap junction protein beta 2(GJB2), and gap junction protein beta 6(GJB6) mutations are considered as the leading congenital causes of deafness. The present study aimed to assess the prevalence of GJB2 and GJB6 mutations in NSHL cases. Materials and Methods This...
متن کاملDiagnostic outcomes of exome sequencing in patients with syndromic or non-syndromic hearing loss
Hereditary hearing loss (HL) is a common sensory disorder, with an incidence of 1-2 per 1000 newborns, and has a genetic etiology in over 50% of cases. It occurs either as part of a syndrome or in isolation and is genetically very heterogeneous which poses a challenge for clinical and molecular diagnosis. We used exome sequencing to seek a genetic cause in a group of 56 subjects (49 probands) w...
متن کاملInvestigating Seven Recently Identified Genes in 100 Iranian Families with Autosomal Recessive Non-syndromic Hearing Loss
Objectives: Hearing loss (HL) is the most common sensory disorder, and affects 1 in 1000 newborns. About 50% of HL is due to genetics and 70% of them are non-syndromic with a recessive pattern of inheritance. Up to now, more than 50 genes have been detected which are responsible for autosomal recessive non-syndromic hearing loss, (ARNSHL). In Iran, HL is one of the most common disabilitie...
متن کاملStudy of frequency and spectrum of GJB2 gene mutations in non-syndromic hearing loss patients of Semnan province
Abstract Background and aim: The frequency of hearing impairment is one out of 500 newborn babies, worldwide. However, in Iran, due to the high prevalence of consanguineous marriages, this amount is estimated to be two to three times higher. So far, more than 120 genes causing non-syndromic Hearing loss (NSHL) have been identified in the world, of which GJB2 gene mutations are the most common c...
متن کاملRelative frequency of GJB2 gene mutations in autosomal recessive non-syndromic hearing loss (ARNSHL) patients in Lorestan population
Background: Congenital hearing loss due to different genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2 (Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. Materials and methods: The aim of this study was to study the frequency of GJB2 Mutations in Lor...
