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.

p.Met895Thr in exon 25 of MYO1A: This variant is not expected to have clinical s ignificance to hearing loss because recent evidence has disqualified an associat ion between variants in the MYO1A gene and hearing loss (Eisenberger 2014). In addition, this variant has been identified in 18/67688 European chromosomes by t he Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs1 48582008), and the methionine (Met) at position 895 is not conserved in mammals or in evolutionarily distant species. -
