Allele specific oligonucleotide analysis of the common deafness mutation 35delG in the connexin 26 (GJB2) gene.
Despite the large number of genes that are expected to be involved in non-syndromal, recessive deafness, only a few have been cloned. One of these genes is GJB2, which encodes connexin 26. A frameshift mutation in this gene has been reported to be common in several populations and a carrier frequency of about 1 in 30 people has been detected in Italy and Spain. Mutation 35delG is difficult to d...
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 کاملVohwinkel Syndrome secondary to missense mutation D66H in GJB2 gene (connexin 26) can include epileptic manifestations
Vohwinkel Syndrome (VS) is a type of diffuse hereditary palmoplantar keratodermas (DHPPK) accompanied by skeletal dimorphisms and sensorineural deafness. The most frequently reported genetic substrate in VS is a point mutation of GJB2 gene, responsible for encoding connexin 26, a gap-junction protein with a crucial role in neuronal migration in rats. We report the case of a 21-year-old male who...
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...
