Abstract

We report a case of a compound heterozygote for adenine phosphoribosyltransferase deficiency (APRT*J/APRT*Q0) leading to 2,8-dihydroxyadenine urolithiasis. Polymerase chain reaction-single strand conformation polymorphism analysis demonstrated that APRT*J and APRT*Q0 alleles from the father and mother, respectively, had been transmitted to the patient. We also reviewed the literature regarding Japanese patients with 2,8-dihydroxyadenine urolithiasis. There seemed to be little difference in clinical course between type 2 homozygotes and compound heterozygotes. However, hemolysate APRT activities of compound heterozygotes were lower than those of type 2 homozygotes.
