Disorders of glyoxylate metabolism

Primary hyperoxaluria, or oxalosis, is a rare metabolic disorder transmitted as an autosomal recessive disease, including both type 1, the most frequent, and type 2, extremely rare. Hyperoxaluria type 1 is due to a defect of the peroxysomal hepatic enzyme L-alanine: glyoxylate aminotransferase (AGT). Hyperoxaluria type 2 is extremely rare and is due to glycerate dehydrogenase deficiency.
