Genetic background of uric acid metabolism in patient with severe chronic tophaceous gout

Popis výsledku v původním jazyce

Hyperuricemia depends on the balance of endogenous production and renal excretion of uric acid. Transporters for urate are located in the proximal tubule where uric acid is secreted and extensively reabsorbed: secretion is principally ensured by the highly variable ABCG2 gene. Enzyme hypoxanthine–guanine phosphoribosyltransferase (HPRT) plays a central role in purine metabolism and its deficiency is an X-linked inherited metabolic disorder associated with clinical manifestations of purine overproduction. Here we report the case of a middle-aged man with severe chronic tophaceous gout with a poor response to allopurinol and requiring repeated surgical intervention. We identified the causal mutations in the HPRT1 gene, variant c.481G > T (p.A161S), and in the crucial urate transporter ABCG2, a heterozygous variant c.421C > A (p.Q141K). This case shows the value of an analysis of the genetic background of serum uric acid.
