Genes affected

MYO6 (HGNC:7605): (myosin VI) This gene encodes a reverse-direction motor protein that moves toward the minus end of actin filaments and plays a role in intracellular vesicle and organelle transport. The protein consists of a motor domain containing an ATP- and an actin-binding site and a globular tail which interacts with other proteins. This protein maintains the structural integrity of inner ear hair cells and mutations in this gene cause non-syndromic autosomal dominant and recessive hearing loss. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2014]

The Asn186Lys variant (MYO6) has not been reported in the literature nor previou sly identified by our laboratory. Computational analyses (biochemical amino acid properties, conservation, PolyPhen2, and SIFT) suggest that the Asn186Lys varia nt may impact the protein, though this information is not predictive enough to d etermine pathogenicity. -
