Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003235344 SCV003934401 uncertain significance not specified 2023-05-09 criteria provided, single submitter clinical testing Variant summary: MYO7A c.3364C>A (p.Leu1122Ile) results in a conservative amino acid change located in the MyTH4 domain (IPR000857) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.9e-05 in 155582 control chromosomes (gnomAD). c.3364C>A has been reported in the literature in the compound heterozygous state in two siblings affected with hearing loss and the variant was observed to segregate with the phenotype in an autosomal recessive inhertiance pattern in the family (Richard_2019). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 36147510, 30303587). Four submitters have provided clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as either VUS (n=3), or pathogenic (n=1). Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic.
