Mutations 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 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 کاملThe p.Cys169Tyr variant of connexin 26 is not a polymorphism
Mutations in the GJB2 gene, which encodes the gap junction protein connexin 26 (Cx26), are the primary cause of hereditary prelingual hearing impairment. Here, the p.Cys169Tyr missense mutation of Cx26 (Cx26C169Y), previously classified as a polymorphism, has been identified as causative of severe hearing loss in two Qatari families. We have analyzed the effect of this mutation using a combinat...
متن کاملConnexin 26 null mice exhibit spiral ganglion degeneration that can be blocked by BDNF gene therapy.
Mutations in the connexin 26 gene (GJB2) are the most common genetic cause of deafness, leading to congenital bilateral non-syndromic sensorineural hearing loss. Here we report the generation of a mouse model for a connexin 26 (Cx26) mutation, in which cre-Sox10 drives excision of the Cx26 gene from non-sensory cells flanking the auditory epithelium. We determined that these conditional knockou...

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 ...
