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 Val3385Ala variant in MYO15A has not been previously reported in individuals with hearing loss, but has been identified in 0.03% (1/4034) of African America n chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.ed u). Computational prediction tools and conservation analyses suggest that the V al3385Ala variant may not impact the protein, though this information is not pre dictive enough to rule out pathogenicity. In summary, the clinical significance of the Val3385Ala variant is uncertain. -

The c.10154T>C (p.V3385A) alteration is located in exon 63 (coding exon 62) of the MYO15A gene. This alteration results from a T to C substitution at nucleotide position 10154, causing the valine (V) at amino acid position 3385 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
