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.Arg721Gln in exon 20 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). Thi s variant has also been identified in 2/67702 of European chromosomes and 1/166 26 South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exa c.broadinstitute.org; dbSNP rs138855953). -
