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:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Arg643Gln in exon 18 of MYO1A: This variant is not expected to have clinical significance because the arginine (Arg) residue at position 643 is not conserved in mammals or across species, with guinea pig and rabbit having a glutamine (Gl n). In addition, recent evidence has disqualified an association between variant s in the MYO1A gene and hearing loss (Eisenberger 2014). This variant has also been identified in 0.5% (1/192) of Kenyan chromosomes by the 1000 Genomes Projec t (rs200450661). -
