Invitae RCV001324651 SCV001515611 uncertain significance Desmin-related myofibrillar myopathy 2020-08-25 criteria provided, single submitter clinical testing 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. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DES-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with asparagine at codon 339 of the DES protein (p.Lys339Asn). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and asparagine.
