Fifty-three loci have presently been reported. The 17 deafness forms for which the genes have been identified are presented. [ommbid.mhmedical.com]

On the other hand, a negative result substantially reduces the likelihood that a syndrome is present, alleviating concerns about the future development of these features. [personalizedmedicine.partners.org]

Deafness, autosomal dominant, 23 (DFNA23) [MIM:605192]: A form of non-syndromic deafness characterized by prelingual, bilateral, symmetric hearing loss with a conductive component present in some but not all patients. [genecards.org]

Hearing loss that is present before a child learns to speak is classified as prelingual or congenital. Hearing loss that occurs after the development of speech is classified as postlingual. [ipfs.io]

Background Hearing loss has an incidence of 1 in 250 births and over half of isolated childhood hearing loss has a genetic etiology, with many genes involved. [personalizedmedicine.partners.org]

Of note, there’s some debate about the molecular etiology of nonsyndromic sensorineural hearing loss in subjects with only one detectable GJB2 mutation. A minority of such cases is explained by digenic etiology of GJB2 with GJB3 or GJB6. [bredagenetics.com]
