Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000156438 SCV000206157 likely pathogenic Rare genetic deafness 2014-09-05 criteria provided, single submitter clinical testing The Ala1070fs variant in MYO6 has not been previously reported in individuals wi th hearing loss or in large population studies. This variant is predicted to cau se a frameshift, which alters the protein's amino acid sequence beginning at cod on 1070 and leads to a premature stop codon 46 codons downstream. This alteratio n is then predicted to lead to a truncated or absent protein. Truncating or loss of function variants in the MYO6 gene have been associated with autosomal reces sive hearing loss as well as autosomal dominant hearing loss (Hilgert 2008, Sang gaard 2008, Neveling 2013, Schrauwen 2013, Volk 2013). Although it has been sugg ested that dominant variants in MYO6 act in a dominant-negative manner (Hilgert 2008), the exact mechanism of pathogenesis has not been fully elucidated. In sum mary, although additional studies are required to fully establish its clinical s ignificance, this variant is likely pathogenic.
