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.

Variant summary: SUOX c.1589G>A (p.Gly530Asp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251320 control chromosomes (gnomAD). c.1589G>A has been reported in the literature in an individual affected with Sulfite Oxidase Deficiency (Kisker_1997). At least one publication reports experimental evidence evaluating an impact on protein function, finding that the variant protein was enzymatically inactive (Wilson_2006). The following publications have been ascertained in the context of this evaluation (PMID: 9428520, 16475804). ClinVar contains an entry for this variant (Variation ID: 3823). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
