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.Met90Thr vari ant in MYO15A has not been previously reported in individuals with hearing loss, but it has been identified in 0.2% (17/7746) of African chromosomes by the Exom e Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs37329426 3). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tool s and conservation analyses suggest that the variant may not impact the protein; however, this data is not sufficient to rule out pathogenicity. In summary, whi le the clinical significance of the p.Met90Thr variant is uncertain, its frequen cy in the general population suggests that it is more likely to be benign. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.269T>C (p.M90T) alteration is located in exon 2 (coding exon 1) of the MYO15A gene. This alteration results from a T to C substitution at nucleotide position 269, causing the methionine (M) at amino acid position 90 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
