Invitae | RCV001225519 | SCV001397802 | uncertain significance | Desmin-related myofibrillar myopathy | 2019-07-26 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Arg350 amino acid residue in DES. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15800015, 17439987). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals with DES-related conditions. This sequence change replaces arginine with leucine at codon 350 of the DES protein (p.Arg350Leu). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and leucine. |
