Genes affected
UROS (HGNC:12592): (uroporphyrinogen III synthase) The protein encoded by this gene catalyzes the fourth step of porphyrin biosynthesis in the heme biosynthetic pathway. Defects in this gene cause congenital erythropoietic porphyria (Gunther's disease). [provided by RefSeq, Jul 2008]
UROS Gene-Disease associations (from GenCC):
  • cutaneous porphyria
