Labcorp Genetics (formerly Invitae), Labcorp RCV001339193 SCV001532914 uncertain significance Sulfite oxidase deficiency due to molybdenum cofactor deficiency type A 2024-02-24 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 59 of the MOCS1 protein (p.Ala59Thr). This variant is present in population databases (rs770756364, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with MOCS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1036216). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The threonine 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.
