Labcorp Genetics (formerly Invitae), Labcorp RCV002574231 SCV002936068 uncertain significance Glycogen storage disease due to lactate dehydrogenase M-subunit deficiency 2022-02-28 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 18 of the LDHA protein (p.Thr18Ile). This variant is present in population databases (rs537487381, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with LDHA-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The isoleucine 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.
