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 Lys858Glu variant in MYO1A has not been reported in the literature nor previ ously identified by our laboratory. Computational analyses (biochemical amino ac id properties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Ly s858Glu variant may impact the protein, though this information is not predictiv e enough to determine pathogenicity. This variant has been identified in 0.01% ( 1/8600) of European American chromosomes in a broad population by the NHLBI Exom e sequencing project (http://evs.gs.washington.edu/EVS/; dbSNP rs142017261). Alt hough this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. In summary, additional data is neede d to determine the clinical significance of this variant. -
