UROD（uroporphyrinogen decarboxylase），癌症关联基因，基因ID：7389，这个基因编码血红素生物合成途径中的一种酶。这种酶通过去除四个羧甲基侧链来催化尿卟啉原转化为粪卟啉原。已知这种酶的突变和缺乏会导致家族性迟发性皮肤卟啉症和肝红细胞性卟啉症。[由Refseq提供，2010年8月]This gene encodes an enzyme in the heme biosynthetic pathway. This enzyme is responsible for catalyzing the conversion of uroporphyrinogen to coproporphyrinogen through the removal of four carboxymethyl side chains. Mutations and deficiency in this enzyme are known to cause familial porphyria cutanea tarda and hepatoerythropoetic porphyria.[provided by RefSeq， Aug 2010]。
