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 p.Ala1452Thr variant in MYO15A has not been previously reported in individua ls with hearing loss, but has been identified in 2/66130 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Althou gh this variant has been seen in the general population, its frequency is not hi gh enough to rule out a pathogenic role. Computational prediction tools and cons ervation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Ala1452Thr variant is un certain. -
