"deafness –associated connexin 26 gene (gjb2) mutations in iranian population"
mutations in the gjb2 gene at the dfnb1 locus on chromosome 13q12 are associated with autosomal recessive non syndromic hearing loss (arnshl) in many populations. a single mutation, at position 35 (35delg) accounts for approximately 30-63% of mutations in white populations with a carrier frequency of 1.5-2.5% in most european, north american and mediterranean populations. in this study we have ...
متن کاملAbsence of mutations in GJB2 (Connexin-26) gene in an ethnic group of southwest Iran
BACKGROUND The common GJB2 gene mutation (35delG) has been previously reported from Iranian patients that were affected with nonsyndromic autosomal recessive deafness. We, therefore, for the first time, investigated the prevalence and frequency of the GJB2 gene mutation in the Iranian deaf population with Arabian origins. MATERIALS AND METHODS We amplified and sequenced the entire coding sequ...
متن کاملMutations in the gene for connexin 26 (GJB2) that cause hearing loss have a dominant negative effect on connexin 30.
Mutations in the gene (GJB2) encoding connexin 26 (cx26) have been linked to sensorineural hearing loss either alone or as part of a syndrome. Here we compare the properties of four cx26 mutants derived from point mutations associated with dominantly inherited hearing loss, either non-syndromic (W44S, R75W) or with various skin disorders (G59A, D66H, R75W). Since cx26 and cx30 are co-localized ...
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 کامل"two novel mutations and predominant 35delg mutation in the connexin 26 gene (gjb2) in iranian populations"
mutations in the gjb2 gene encoding connexin 26 (cx26) protein are a major cause for autosomal recessive non syndromic and sporadic deafness in many populations. in this study we have investigated the prevalence of the gjb2 gene mutations using nested pcr pre screening strategy and direct sequencing method. two hundred and sixty autosomal recessive non syndromic and sporadic deaf subjects from ...
