Genes affected
XDH (HGNC:12805): (xanthine dehydrogenase) Xanthine dehydrogenase belongs to the group of molybdenum-containing hydroxylases involved in the oxidative metabolism of purines. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. Xanthine dehydrogenase can be converted to xanthine oxidase by reversible sulfhydryl oxidation or by irreversible proteolytic modification. Defects in xanthine dehydrogenase cause xanthinuria, may contribute to adult respiratory stress syndrome, and may potentiate influenza infection through an oxygen metabolite-dependent mechanism.

Xanthinuria type II Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 09, 2022This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 121 of the XDH protein (p.Val121Ile). This variant is present in population databases (rs751332444, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with XDH-related conditions. ClinVar contains an entry for this variant (Variation ID: 576475). 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 disruptive. 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. -
