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.

Hereditary xanthinuria type 1 Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJul 27, 2017The p.Ser1147X (NM_000379.3 c.3440C>G) variant in XDH has not been previously re ported in the literature and was absent from large population studies. This nons ense variant leads to a premature termination codon at position 1147, which is p redicted to lead to a truncated or absent protein. Biallelic loss of function of the XDH gene has been associated with hereditary xanthinuria type I. In summary , although additional studies are required to fully establish a null effect on t he protein, the p.Ser1147X variant in the XDH gene is likely pathogenic for here ditary xanthinuria type I in an autosomal recessive manner based on its predicte d impact on the protein. -
