"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 کاملConnexin 26 studies in patients with sensorineural hearing loss.
OBJECTIVE To determine the spectrum of connexin 26 (Cx26) mutations and their phenotypes in children with sensorineural hearing loss (SNHL) or mixed hearing loss (MHL). DESIGN Children with SNHL or MHL were prospectively tested for mutations in the entire coding region of the Cx26 gene. PATIENTS Children with SNHL or MHL with no obvious etiology for the hearing loss. RESULTS Between Decem...
متن کاملMutation Analysis of Connexin 26 Gene and Del (GJB6-D13S1830) in Patients with Hereditary Deafness from Two Provinces in Iran
Mutations in the connexin 26 (Cx26) gene at the DFNB1 locus on chromosome 13q12 are associated with autosomal recessive non-syndromic hearing loss (ARNSHL). There are many known mutations in this gene that cause hearing loss. A single frameshift, at position 35 (35delG) accounts for 50% of mutations in the Caucasian population with carrier frequencies of 1.5-2.5%. In this study we investigated ...
متن کاملA genotype-phenotype correlation for GJB2 (connexin 26) deafness.
INTRODUCTION Mutations in GJB2 are the most common cause of non-syndromic autosomal recessive hearing impairment, ranging from mild to profound. Mutation analysis of this gene is widely available as a genetic diagnostic test. OBJECTIVE To assess a possible genotype-phenotype correlation for GJB2. DESIGN Retrospective analysis of audiometric data from people with hearing impairment, segregat...
متن کاملRevertant mosaicism repairs skin lesions in a patient with keratitis-ichthyosis-deafness syndrome by second-site mutations in connexin 26
Revertant mosaicism (RM) is a naturally occurring phenomenon where the pathogenic effect of a germline mutation is corrected by a second somatic event. Development of healthy-looking skin due to RM has been observed in patients with various inherited skin disorders, but not in connexin-related disease. We aimed to clarify the underlying molecular mechanisms of suspected RM in the skin of a pati...
