Abstract
Type 1 xanthinuria is a rare cause of urolithiasis due to xanthine dehydrogenase deficiency. Pediatric cases are exceptional. Through the genetic analysis of two cases, we discovered three mutations responsible for a loss of enzyme activity. The first one had a C.3536T>C missense mutation in the XDH gene and the other one was heterozygous for two mutations c.700+1G>T and c.31778_82delTCAT. We review the diagnostic methods, possible complications, and preventive measures for stone formation.
