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 Arg31His variant in MYO1A has not been reported in individuals with hearing loss or in large population studies. Computational analyses (biochemical amino a cid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) ) do not provide s trong support for or against an impact to the protein. In summary, additional da ta is needed to determine the clinical significance of this variant. -
