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]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Cys3229Tyr variant in MYO15A has not been previously reported in individua ls with hearing loss, but has been identified in 8/30782 South Asian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org/; dbSNP rs780798446). Computational prediction tools and conservation analysis sug gest that the variant may impact the protein, though this information is not pre dictive enough to determine pathogenicity. In summary, the clinical significanc e of the p.Cys3229Tyr variant is uncertain. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.9686G>A (p.C3229Y) alteration is located in exon 59 (coding exon 58) of the MYO15A gene. This alteration results from a G to A substitution at nucleotide position 9686, causing the cysteine (C) at amino acid position 3229 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
