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 p.Glu3061Lys va riant in MYO15A has been previously reported by our laboratory in two individual s with hearing loss, but a variant affecting the second copy of the gene was not identified in either individual. This variant has been identified in 0.28% (66/ 23988) of African chromosomes by the Genome Aggregation Database (gnomAD, http:/ /gnomad.broadinstitute.org; dbSNP rs116833707). Although this variant has been s een in the general population, its frequency is not high enough to rule out a pa thogenic role. Computational prediction tools and conservation analysis do not p rovide strong support for or against an impact to the protein. In summary, while the clinical significance of the p.Glu3061Lys variant is uncertain, its frequen cy in the general population suggests that it is more likely to be benign.
