Summaries for Deafness, X-Linked 2

OMIM® : 57 DFNX2, also known as DFN3, is an X-linked recessive disorder characterized by progressive conductive and sensorineural hearing loss and a pathognomonic temporal bone deformity that includes dilatation of the inner auditory canal and a fistulous connection between the internal auditory canal and the cochlear basal turn, resulting in a perilymphatic fluid 'gusher' during stapes surgery (summary by de Kok et al., 1995 and Song et al., 2010). See also choroideremia, deafness, and mental retardation (303110), a contiguous gene deletion syndrome involving the POU3F4 and CHM (300390) genes on Xq21; isolated choroideremia (303100) is caused by mutation in the CHM gene. (304400) (Updated 05-Mar-2021)

MalaCards based summary : Deafness, X-Linked 2, also known as nance deafness, is related to deafness, x-linked 1 and nonsyndromic hearing loss. An important gene associated with Deafness, X-Linked 2 is POU3F4 (POU Class 3 Homeobox 4), and among its related pathways/superpathways is Gap junction trafficking. Affiliated tissues include bone and brain, and related phenotypes are conductive hearing impairment and stapes ankylosis

Disease Ontology : 12 An X-linked nonsyndromic deafness characterized by progressive conductive and sensorineural hearing loss and pathognomonic inner ear anomalies that has material basis in hemizygous or homozygous mutation in POU3F4 or upstream regulatory elements of this gene on chromosome Xq21.1.

UniProtKB/Swiss-Prot : 73 Deafness, X-linked, 2: A form of deafness characterized by both conductive hearing loss resulting from stapes (perilymphatic gusher) fixation, and progressive sensorineural deafness.
