Genetics of Hearing Loss--Nonsyndromic

Otolaryngol Clin North Am. 2015 Dec;48(6):1063-72. doi: 10.1016/j.otc.2015.06.005. Epub 2015 Aug 11.


Eighty percent of nonsyndromic hearing losses are caused by autosomal-recessive (AR) inheritance, while most of the other 20% are caused by autosomal-dominant (AD) inheritance. Although AR nonsyndromic SNHL is most commonly caused by GJB2 and SLC26A4, there is no single gene that accounts for any significant proportion of AD SNHL. High-throughput sequencing techniques, also called next-generation sequencing (NGS) or massively parallel sequencing (MPS), may allow for routine definitive diagnosis of all possible genetic causes for hearing loss in the not-too-distant future.
