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 p.Asn903Ser variant in MYO1A has not been reported in individuals with heari ng loss, but has been identified in 0.012% (1/8600) of European American chromos omes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; d bSNP rs146373415). Although this variant has been seen in the general population , its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Asn903Ser variant is uncertain. -
