Porphyria cutanea tarda (PCT) is the most common human porphyria, due to hepatic deficiency of uroporphyrinogen decarboxylase (UROD), which is acquired in the presence of iron overload and various susceptibility factors, such as alcohol abuse, smoking, hepatitis C virus (HCV) infection, HIV infection, iron overload with HFE gene mutations, use of estrogens, and UROD mutation.

We have so far identified 50 different mutations among 4 genes associated with the most common porphyrias showing a high molecular heterogeneity: 22 in the hydroxymethylbilane synthase (HMBS) gene (AIP), 7 in the protoporphyrinogen oxidase (PPOX) gene (VP), 16 in the uroporphyrinogen decarboxylase (UROD) gene (PCT) and 5 in the ferrochelatase (FECH) gene (EPP).
