Among them, several myosin genes are known to cause both syndromic and non-syndromic hearing loss (MYO7A, DFNA11 [3]; DFNB2 [4]; Usher syndrome type 1B [5]; MYH9, DFNA17 [6]; MYH9-related disorder [7]; MYH14, DFNA4 [8]; peripheral neuropathy, myopathy, hoarseness, and hearing loss [9]; MYO6, DFNA22 [10], DFNB37 [11]; MYO3A, DFNB30 [12]; MYO15A, DFNB3 [13]). This evidence concerns the gene MYO15A and myopathy.
