Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000038290 SCV000061959 likely pathogenic Rare genetic deafness 2018-07-18 criteria provided, single submitter clinical testing The Tyr705fs variant in MYO6 has been reported by our laboratory in 1 individual with hearing loss and segregated in two affected family members (this family). It was absent from large population studies. This frameshift variant is expected to alter the protein?s amino acid sequence beginning at position 705 and lead t o a premature termination codon 9 amino acids downstream. This alteration is the n predicted to lead to a truncated or absent protein. Loss-of-function variants in the MYO6 gene have been strongly associated to autosomal dominant hearing los s (Sanggaard 2008, Cheng 2014, Miyagawa 2015, Yang 2013, Volk 2013), and there i s also evidence that biallelic occurrence may result in a more severe hearing lo ss (Ahmed 2003, Yan 2016, Yang 2013 ). In summary, this variant is likely pathog enic for autosomal dominant hearing loss, though additional studies are required to fully establish its clinical significance.
