Pathway Description
AICA-Ribosiduria
Homo sapiens
Disease Pathway
AICA-ribosiduria is a metabolic disease caused by a defect in final steps of purine de novo biosynthesis. This defect is caused by a mutation in the ATIC which codes for bifunctional purine biosynthesis protein PURH. A deficiency in this enzyme results in accumulation of 5-aminoimidazole-4-carboxamide in urine. Symptoms include mental retardation, epilepsy, dysmorphic features, and congenital blindness.
