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

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.64).
BP6
Variant 17-18151405-C-T is Benign according to our data. Variant chr17-18151405-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 164550.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Benign=1, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=1.38 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000459 (70/152342) while in subpopulation AMR AF= 0.00438 (67/15302). AF 95% confidence interval is 0.00354. There are 1 homozygotes in gnomad4. There are 49 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
