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 c.6957-13C>A va riant in MYO15A has not been previously reported in individuals with hearing los s, but has been identified in 1/11090 Latino chromosomes by the Exome Aggregatio n Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs773985638). This var iant is located in the 3' splice region. Computational tools do not suggest an i mpact to splicing; however, this information is not predictive enough to rule ou t pathogenicity. In summary, the clinical significance of the c.6957-13C>A varia nt is uncertain. -
