• NM_004999.4:c.475G>A

Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BA1

This summary comes from the ClinGen Evidence Repository: The c.475G>A variant in MYO6 is a missense variant predicted to cause substitution of glutamic acid by lysine at amino acid 159 (p.Glu159Lys).​ The filtering allele frequency of this variant is 0.013% for South Asian chromosomes by the Genome Aggregation Database v4 (18/91064 with 95% CI), which meets no population allele frequency criteria (PM2_Supporting, BS1, and BA1 are not met). However, this variant is also present in 0.8% (257/29596) of Ashkenazi Jewish chromosomes, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen Hearing Loss Expert Panel for autosomal dominant hearing loss variants (BA1). This variant has not been reported in the literature in individuals affected with hearing loss. Therefore, given the lack of contradictory evidence, this variant is classified as benign based on the ACMG/AMP criteria applied, as specified by the Hearing Loss Expert Panel: BA1. (ClinGen Hearing Loss VCEP specifications version 2; 01.15.2025). LINK:https://erepo.genome.network/evrepo/ui/classification/CA135641/MONDO:0019497/005

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]
