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]

p.Leu292Ser in exon 10 of MYO6: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, 4 mammals (naked mole rat, guinea pig, brush-tailed rat, and David's myotis bat) have a serine (Ser) at this position despite high nearby amino acid conser vation. In addition, it has been identified in 0.2% (54/34408) of Latino chromos omes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.or g; dbSNP rs144038082). -
