Labcorp Genetics (formerly Invitae), Labcorp RCV002561214 SCV001377385 uncertain significance not provided 2022-08-09 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 588 of the MUT protein (p.Arg588Leu). This variant is present in population databases (rs141829043, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with MUT-related conditions. ClinVar contains an entry for this variant (Variation ID: 937137). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
Fulgent Genetics, Fulgent Genetics RCV001206094 SCV002775287 uncertain significance Methylmalonic aciduria due to methylmalonyl-CoA mutase deficiency 2022-02-02 criteria provided, single submitter clinical testing
Ambry Genetics RCV004827795 SCV005447091 uncertain significance not specified 2024-08-19 criteria provided, single submitter clinical testing The c.1763G>T (p.R588L) alteration is located in exon 10 (coding exon 9) of the MUT gene. This alteration results from a G to T substitution at nucleotide position 1763, causing the arginine (R) at amino acid position 588 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
