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]

Variant classified as Uncertain Significance - Favor Benign. The p.Pro3009Ser va riant in MYO15A has not been previously reported in individuals with hearing los s, but has been identified in 1/11572 Latino chromosomes by the Exome Aggregatio n Consortium (ExAC, http://exac.broadinstitute.org). Although this variant has b een seen in the general population, its frequency is not high enough to rule out a pathogenic role. The proline (Pro) at position 3009 is not conserved in mamma ls or evolutionarily distant species with 2 mammals (prairie vole and guinea pig ) having a serine (Ser) at this position, suggesting that the variant may be tol erated. Additional computational prediction tools do not provide strong support for or against an impact to the protein. In summary, the clinical significance o f this variant cannot be determined with certainty; however, the conservation da ta suggests that it is more likely to be benign. -
