UMPS_HUMAN Defects in UMPS are the cause of orotic aciduria type 1 (ORAC1) [MIM:258900. A disorder of pyrimidine metabolism resulting in megaloblastic anemia and orotic acid crystalluria that is frequently associated with some degree of physical and mental retardation. A minority of cases have additional features, particularly congenital malformations and immune deficiencies.[1]
