Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_016239.4(MYO15A):c.9997C>G(p.Arg3333Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000623 in 1,604,072 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R3333Q) has been classified as Likely benign.

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.Arg3333Gly va riant in MYO15A has not been previously reported in individuals with hearing los s, but has been identified in 5/16458 South Asian chromosomes by the Exome Aggre gation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs765670344). Arg inine (Arg) at position 3333 is not conserved in mammals or evolutionarily dista nt species, raising the possibility/supporting that a change at this position ma y be tolerated. In summary, while the clinical significance of the p.Arg3333Gly variant is uncertain, these data suggest that it is more likely to be benign. -
