GeneDx RCV001570413 SCV001794704 uncertain significance not provided 2019-08-12 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp RCV002570775 SCV003442097 uncertain significance Lipoic acid synthetase deficiency 2022-08-01 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 297 of the LIAS protein (p.Arg297Cys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LIAS-related conditions. ClinVar contains an entry for this variant (Variation ID: 1204145). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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.
