Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000844720 SCV000059779 pathogenic Rare genetic deafness 2011-07-26 criteria provided, single submitter clinical testing The Lys1255fs variant in MYO7A has been reported in two probands with Usher synd rome who were each compound heterozygous with a second pathogenic MYO7A variant (Roux 2011, Jaijo 2007). In addition, the Lys1255fs variant is predicted to caus e a frameshift, which alters the protein's amino acid sequence beginning at codo n 1255 and leads to a premature stop codon 8 codons downstream. This alteration is then predicted to lead to a truncated or absent protein. In summary, this var iant meets our criteria to be classified as pathogenic.

Invitae RCV001785455 SCV002230098 pathogenic not provided 2023-11-30 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Lys1255Argfs*8) in the MYO7A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MYO7A are known to be pathogenic (PMID: 8900236, 25404053). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of autosomal recessive MYO7A-related conditions (PMID: 17361009, 26969326, 27460420, 30337596, 31479088). This variant is also known as c.3763del. ClinVar contains an entry for this variant (Variation ID: 43223). For these reasons, this variant has been classified as Pathogenic.
