Labcorp Genetics (formerly Invitae), Labcorp RCV002018537 SCV002303859 uncertain significance Nemaline myopathy 8 2021-05-30 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with KLHL40-related conditions. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with phenylalanine at codon 518 of the KLHL40 protein (p.Val518Phe). The valine residue is moderately conserved and there is a small physicochemical difference between valine and phenylalanine.
