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 was made for transcript

Our verdict: Benign. The variant received -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.75).
BP6
Variant 17-18152126-C-T is Benign according to our data. Variant chr17-18152126-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 45762.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-4.37 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.00204 (2852/1399070) while in subpopulation NFE AF = 0.0024 (2590/1079008). AF 95% confidence interval is 0.00232. There are 2 homozygotes in GnomAdExome4. There are 1377 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
