Mutations of the Connexin 26 gene in families with non-syndromic hearing loss.
Autosomal recessive non-syndromic hearing impairment (ARNSHI) is caused by mutations in the gap junction gene GJB2 (Connexin 26; Cx26) in numerous human populations. The aim of this study was to determine the frequency of six GJB2 mutations in 50 Syrian families with congenital deafness and in 180 controls. PCR-RFLP was used to detect the 35delG, 167delT, M34T, W24X, W77R and E47X mutations, an...
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 کاملScreening of Connexin 26 in Nonsyndromic Hearing Loss
Introduction The first locus for nonsyndromic autosomal recessive hearing loss is on chromosome 13q11-22. The 35delG mutation is present in 80% of cases in which GJB2 is involved, which makes the study of this mutation very important. The viability and benefits of screening for mutations in the connexin 26 gene are now beginning to change the diagnostic evaluation and identification of the etio...
متن کاملConnexin 26 and autosomal recessive non-syndromic hearing loss
It has long been recognized that heredity plays a major role in hearing impairment. Although the facts about the genetic basis of hearing loss have fascinated both clinicians and geneticists for a long time, it is only within the last few years that the genes and molecular mechanisms underlying deafness have begun to be discovered. There is a great deal of genetic heterogeneity in deafness. Thi...
متن کاملConnexin 26 Gene Mutations in Non-Syndromic Hearing Loss Among Kuwaiti Patients
OBJECTIVE To study connexin 26 (Cx26) gene mutations among autosomal recessive non-syndromal hearing loss in Kuwaiti patients and evaluate their effect on phenotypes. SUBJECTS AND METHODS This cross sectional study included 100 patients aged between 6 months and 18 years, who were referred to the Sheikh Salem Al-Ali Centre for audiology and speech evaluation of autosomal recessive non-syndrom...
