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.4656-11delC v ariant in MYO15A has not been previously reported in individuals with hearing lo ss, but it has been identified in 5/9804 African chromosomes by the Exome Aggreg ation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs767773802). This variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing. However, this information is not predictive enough to rul e out pathogenicity. In summary, while the clinical significance of this variant is uncertain, these data suggest that it is more likely to be benign. -
