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.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. -
