Genes affected

MYO15A (HGNC:7594): (myosin XVA) This gene encodes an unconventional myosin. This protein differs from other myosins in that it has a long N-terminal extension preceding the conserved motor domain. Studies in mice suggest that this protein is necessary for actin organization in the hair cells of the cochlea. Mutations in this gene have been associated with profound, congenital, neurosensory, nonsyndromal deafness. This gene is located within the Smith-Magenis syndrome region on chromosome 17. Read-through transcripts containing an upstream gene and this gene have been identified, but they are not thought to encode a fusion protein. Several alternatively spliced transcript variants have been described, but their full length sequences have not been determined. [provided by RefSeq, Jul 2008]

The Met2802Val variant in MYO15A has not been reported in affected individuals o r in large population studies. Computational analyses (biochemical amino acid pr operties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the variant may not impact the protein, particularly given a lack of amino acid conservatio n at the Met2802 site including a Val residue in another mammal. However, we can not rule out pathogenicity, especially in light of the existing MYO15A variant i dentified. In summary, the clinical significance of this variant cannot be deter mined with certainty. We recommend parental testing to assess cis/trans configur ation with the other MYO15A variant. -
