Genes affected

MYO1A (HGNC:7595): (myosin IA) This gene encodes a member of the myosin superfamily. The protein represents an unconventional myosin; it should not be confused with the conventional skeletal muscle myosin-1 (MYH1). Unconventional myosins contain the basic domains characteristic of conventional myosins and are further distinguished from class members by their tail domains. They function as actin-based molecular motors. Mutations in this gene have been associated with autosomal dominant deafness. Alternatively spliced variants have been found for this gene.

The Pro560Ala variant in MYO1A has not been previously reported in individuals w ith hearing loss, but has been identified in 0.02% (2/8600) of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu /EVS/; dbSNP rs140586750). Although this variant has been seen in the general po pulation, its frequency is not high enough to rule out a pathogenic role. Comput ational prediction tools and conservation analyses suggest that the Pro560Ala va riant may impact the protein, though this information is not predictive enough t o determine pathogenicity. In summary, the clinical significance of the Pro560Al a variant is uncertain. -
