Summaries for Deafness, Autosomal Dominant 2b

About this section
Disease Ontology : 12 An autosomal dominant nonsyndromic deafness that is characterized postlingual onset in the fourth decade of life with by high frequency progressive hearing loss and has material basis in mutation in the GJB3 gene on chromosome 1p34.3.

MalaCards based summary : Deafness, Autosomal Dominant 2b, also known as dfna2b, is related to nonsyndromic deafness and hypotrichosis-deafness syndrome. An important gene associated with Deafness, Autosomal Dominant 2b is GJB3 (Gap Junction Protein Beta 3). Related phenotypes are high-frequency hearing impairment and hearing/vestibular/ear

UniProtKB/Swiss-Prot : 73 Deafness, autosomal dominant, 2B: A form of non-syndromic sensorineural deafness characterized by progressive high frequency hearing loss in adulthood, with milder expression in females.
