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]

ACMG classification

Specifications for MYO15A are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.9).

BP6

Variant 17-18136486-G-A is Benign according to our data. Variant chr17-18136486-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 164521.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00157 (239/152274) while in subpopulation EAS AF = 0.0247 (128/5180). AF 95% confidence interval is 0.0212. There are 1 homozygotes in GnomAd4. There are 140 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 10 AR gene
