GeneDx RCV000481772 SCV000566126 uncertain significance not provided 2017-02-16 criteria provided, single submitter clinical testing The R37G variant of uncertain significance in the DES gene has not been published as pathogenic or been reported as benign to our knowledge. R37G is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R37G variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In addition, this substitution occurs at a position that is conserved in mammals. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function.
Invitae RCV001203491 SCV001374658 uncertain significance Desmin-related myofibrillar myopathy 2022-05-14 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 37 of the DES protein (p.Arg37Gly). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with DES-related conditions. ClinVar contains an entry for this variant (Variation ID: 418796). 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: "Not Available"; Align-GVGD: "Class C0"). 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.
