Primary hyperoxaluria type 1 (PH1) is a rare autosomal recessive metabolic disorder caused by a deficiency of the peroxisomal enzyme alanine-glyoxylate aminotransferase. This deficiency results in an overproduction of oxalate by the liver. Excess oxalate leads to urolithiasis, nephrocalcinosis, and renal failure. Additionally, end-stage kidney disease (ESKD) occurs in approximately 50% of adults diagnosed with this condition. Presently, combined liver and renal transplant is the only curative option.
