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]

  Hearing Loss Testing Requisition Form Hearing impairment is the most frequent sensory deficit in humans. It affects 1 in 500 newborns and 50% of octogenarians and in aggregate affects 360 million people worldwide. [morl.lab.uiowa.edu]

  For PTA, the levels of hearing loss are described as follows: ~20 dB is assigned as normal hearing; 21–40 dB as mild hearing impairment; 41–70 dB as moderate hearing impairment; 71–95 dB as severe hearing impairment; and >95 dB as profound hearing impairment [bmcmedgenet.biomedcentral.com]

  Non-syndromal sensorineural hearing impairment in humans is genetically heterogeneous showing autosomal recessive, autosomal dominant, X-linked or mitochondrial modes of transmission. DFNB9 is caused by mutations in the OTOF gene. [cags.org.ae]

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]
