Frequency of c.35delG Mutation in GJB2 Gene (Connexin 26) in Syrian Patients with Nonsyndromic Hearing Impairment
Background Hearing impairments (HI) are the most common birth defect worldwide. Very large numbers of genes have been identified but the most profound is GJB2. The clinical interest regarding this gene is very pronounced due to its high carrier frequency (0.5-5.4%) across different ethnic groups. This study aimed to determine the prevalence of common GJB2 mutations in Syrian patients with profo...
متن کاملA common founder for the 35delG GJB2 gene mutation in connexin 26 hearing impairment.
Fifty to eighty percent of autosomal recessive congenital severe to profound hearing impairment result from mutations in a single gene, GJB2, that encodes the protein connexin 26. One mutation of this gene, the 35delG allele, is particularly common in white populations. We report evidence that the high frequency of this allelic variant is the result of a founder effect rather than a mutational ...
متن کاملAnalysis of GJB2 (Connexin 26) Mutation in Patients with Congenital Non-Syndromic Sensorineural Hearing Loss
South European cases with autosomal recessive inherited hearing loss (4,8). The frequent incidence of the 35delG mutation requires analyzing both affected individuals and parents (in terms of being carriers) for genetic counseling. The aim of this study was to determine the frequency of GJB2 gene mutations in patients with congenital NSSNHL and to investigate new mutations of the GJB2 gene in o...
متن کاملreport of a new mutation and frequency of connexin 26 gene (gjb2) mutations in patients from three provinces of iran
autosomal recessive and sporadic non-syndromic hearing loss (arsnshl) is the major form of hereditary deafness.mutations in the gjb2 gene encoding the gap-junction protein connexin 26 have been identified to be highly associated with arsnshl. in this study we have analyzed 196 deaf subjects from 179 families having one or more deaf children in 3 proviences of iran, including kordestan, khuzesta...
متن کاملRelative Frequency of 35delG Mutation in GJB2 Gene in Autosomal Recessive Non-Syndromic Hearing Loss (ARNSHL) Patients in Kerman Population
Congenital hearing loss with many 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. The aim of this study was to study the frequency of one mutation (35delG) of GJB2 gene in Kerman non-syndromic deaf p...
