Genes affected

MYO6 (HGNC:7605): (myosin VI) This gene encodes a reverse-direction motor protein that moves toward the minus end of actin filaments and plays a role in intracellular vesicle and organelle transport. The protein consists of a motor domain containing an ATP- and an actin-binding site and a globular tail which interacts with other proteins. This protein maintains the structural integrity of inner ear hair cells and mutations in this gene cause non-syndromic autosomal dominant and recessive hearing loss. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.74).

BP6

Variant 6-75886931-C-T is Benign according to our data. Variant chr6-75886931-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 178474.

BP7

Synonymous conserved (PhyloP=0.008 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000914 (139/152008) while in subpopulation AFR AF = 0.0033 (137/41468). AF 95% confidence interval is 0.00285. There are 0 homozygotes in GnomAd4. There are 65 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
