Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4BS1_Supporting

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency (the lower threshold of the 95% CI of 64/23748) of the c.1582G>A (p.Gly528Ser) variant in the MYO15A gene is 0.217% for African/African-American chromosomes by gnomAD, which is a higher frequency than would be expected for an autosomal recessive pathogenic variant based on the thresholds defined by the ClinGen Hearing Loss Expert Panel (BS1_Supporting). Additionally, computational prediction analysis using the metapredictor tool REVEL suggests that the variant may not impact the protein (BP4). In summary, this variant meets criteria to be classified as likely benign. ACMG/AMP criteria applied, as specified by the Hearing Loss Expert Panel: BS1_Supporting, BP4.

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]

The c.1582G>A (p.G528S) alteration is located in exon 2 (coding exon 1) of the MYO15A gene. This alteration results from a G to A substitution at nucleotide position 1582, causing the glycine (G) at amino acid position 528 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

p.Gly528Ser in exon 2 of MYO15A: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, 3 mammals (naked mole-rat, chinchilla, and brush-tailed rat) have a serine (Ser) at this position despite high nearby amino acid sequence conservation. In addition, other computational tools do not suggest an impact to the protein. It has been identified in 0.3% (65/23654) of African chromosomes by the Genome Agg regation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs199695398). -
