- Abstract
Hepatoerythropoietic porphyria (HEP) is an uncommon inherited cutaneous porphyria, related to porphyria cutanea tarda, that results from severe uroporphyrinogen decarboxylase (UROD) deficiency. It is characterized clinically by the onset in early childhood of severe lesions on sun-exposed skin. We describe a man aged 38 years with an unusually mild form of the disease that started in his early teens. Our data confirm that homozygosity for the F46L mutation in the UROD gene causes a mild form of HEP and show that this genotype may be associated with a unique urinary porphyrin excretion pattern in which pentacarboxylic porphyrin predominates.
