MalaCards based summary: Dfnb1, also known as deafness nonsyndromic, connexin 26 linked, is related to sensorineural hearing loss and nonsyndromic deafness. An important gene associated with Dfnb1 is GJB2 (gap junction protein, beta 2, 26kDa), and among its related pathways are Gap junction trafficking and Myometrial Relaxation and Contraction Pathways. The compounds 10panx and gap 27 have been mentioned in the context of this disorder. Affiliated tissues include testes, and related mouse phenotypes are nervous system and hearing/vestibular/ear.
