Definition

Autosomal dominant deafness-7 (DFNA7) is a form of progressive sensorineural hearing loss with highly variable age at onset and severity, even within families. The age at onset ranges from congenital to mid-adulthood. Some patients may have associated vertigo (summary by Wesdorp et al., 2018). [from OMIM]
