Disease

PUR9_HUMAN Defects in ATIC are the cause of AICAR transformylase/IMP cyclohydrolase deficiency (AICAR) [MIM:608688. A neurologically devastating inborn error of purine biosynthesis. Patients excrete massive amounts of AICA-riboside in the urine and accumulate AICA-ribotide and its derivatives in erythrocytes and fibroblasts. AICAR causes profound mental retardation, epilepsy, dysmorphic features and congenital blindness.^[1] ^[2]

Function

PUR9_HUMAN Bifunctional enzyme that catalyzes 2 steps in purine biosynthesis.^[3]
