Genes affected

SUOX (HGNC:11460): (sulfite oxidase) Sulfite oxidase is a homodimeric protein localized to the intermembrane space of mitochondria. Each subunit contains a heme domain and a molybdopterin-binding domain. The enzyme catalyzes the oxidation of sulfite to sulfate, the final reaction in the oxidative degradation of the sulfur amino acids cysteine and methionine. Sulfite oxidase deficiency results in neurological abnormalities which are often fatal at an early age. Alternative splicing results in multiple transcript variants encoding identical proteins.

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 311 of the SUOX protein (p.Glu311Lys). This variant is present in population databases (rs778950352, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with SUOX-related conditions. ClinVar contains an entry for this variant (Variation ID: 576378). 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 tolerated. 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. -
