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]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Jun 20, 2013

The p.Phe1616Leu variant in MYO15A has not been reported in individuals with hea ring loss, but has been identified in 4/65798 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs368430972) . Computational analyses (biochemical amino acid properties, conservation, Align GVGD, PolyPhen2, and SIFT) do not provide strong support for or against an impac t to the protein. In summary, the clinical significance of this variant cannot b e determined without additional data. -
