The c.3527G>A variant in MYO7A is a missense variant predicted to cause substitution of serine by asparagine at amino acid 1176. The highest population minor allele frequency in gnomAD v4.1 is 0.0005863 (44/75046 alleles) in the African/African-American population (PM2_Supporting and BS1_Supporting are not met). The computational predictor REVEL gives a score of 0.638, which is neither above nor below the thresholds predicting a damaging or benign impact on MYO7A function (PP3 not met). The variant has been observed in at least 3 individuals with Usher syndrome type 1. However, in one proband the c.3527G>A variant in the homozygous state was observed with another homozygous pathogenic/likely pathogenic variant in MYO7A (BP2 met; PMID: 26969326). The remaining probands did not have a second pathogenic/likely pathogenic variant in MYO7A identified (PM3 and PP4 not met; PMID: 27344577, 27460420, 31479088). While this variant has also been identified in individuals with hearing loss, they either had no other pathogenic/likely pathogenic variant or an alternate molecular basis for disease was identified (PMID:33297549, LabCorp Genetics (formerly Invitae) internal data ClinVar SCV001418817.4, GeneDx internal data ClinVar SCV000714448.1). In summary, this variant has been classified as a variant of uncertain significance for autosomal recessive Usher syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen Hearing Loss VCEP: BP2 (ClinGen Hearing Loss VCEP specifications version 2; 12/18/2024).
