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.Arg1935Gly variant in MYO15A has not been previously reported in individua ls with hearing loss. This variant has been identified in 10/62318 European chro mosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.or g; dbSNP rs200041829); however, this frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses do not provide strong evidence for or against an impact to the protein. In summary, th e clinical significance of the p.Arg1935Gly variant is uncertain. -
