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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMay 28, 2016Variant classified as Uncertain Significance - Favor Benign. The c.4038+6_4038+7 delCA variant in MYO15A has not been previously reported in individuals with hea ring loss, but it has been identified in 6/9798 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org;); however, its fr equency is not high enough to rule out a pathogenic role. Several other inserti ons and deletions in this region have been reported at low frequency by ExAC. T his variant is located in the 5' splice region. Computational tools do not sugge st an impact to splicing. However, this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the c.403 8+6_4038+7delCA variant is uncertain, these data suggest that it is more likely to be benign. -
