Primary hyperoxaluria type 1 (PH1) is a rare inherited metabolic disorder that is caused by a deficiency of the peroxisomal enzyme alanine-glyoxylate aminotransferase. This deficiency results in an overproduction of oxalate by the liver, which leads to urolithiasis, nephrocalcinosis, and renal failure. In as many as 50% of patients, end-stage kidney disease (ESKD) occurs by the fourth decade of life. Presently, combined liver and renal transplant is the only curative option.
