Xantinúria é uma doença autossômica recessiva rara associada a uma deficiência na xantina desidrogenase (XDH - também conhecida como xantina oxidorredutase, XOR), que normalmente catalisa a conversão de hipoxantina e xantina em ácido úrico. Em humanos, o NAD+ é o receptor de elétrons e a atividade significativa está restrita a fígado e mucosa intestinal. A conversão irreversível em oxidase ocorre durante isquemia. O acúmulo/excreção preferencial de xantina em plasma e urina resulta da extensa reciclagem de hipoxantina pela via de salvamento para a qual a xantina não é um substrato em humanos: excesso de xantina derivado da guanina via guanina desaminase.
