Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 1P and 7B. PP3BP4_ModerateBP6BS1

The NM_004999.4(MYO6):c.3530G>A(p.Arg1177His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00017 in 1,614,064 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1177C) has been classified as Likely benign.

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: Likely_benign. The variant received -6 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 7: BayesDel_noAF, Cadd, Eigen, phyloP100way_vertebrate, PrimateAI, REVEL, REVEL [when BayesDel_addAF, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.20197463).

BP6

Variant 6-75914153-G-A is Benign according to our data. Variant chr6-75914153-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 289702.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000894 (136/152172) while in subpopulation AFR AF = 0.00318 (132/41532). AF 95% confidence interval is 0.00274. There are 1 homozygotes in GnomAd4. There are 72 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
