Myosin VIIa (MYO7A) belongs to the unconventional myosin superfamily that is vital for proper differentiation and development of stereocilia bundles [125], and MYO7A mutations in patients are associated with DFNB2, DFNA11, and usher syndrome (USH, genetically heterogenous disorder characterized by retinitis pigmentosa and HL) type 1B (USH1B) [126, 127]. Here, MYO7A is linked to autosomal dominant nonsyndromic hearing loss 11.
