to test this hypothesis the enzymes responsible for these conditions , protoporphyrinogen oxidase ( variegate porphyria ) and uroporphyrinogen decarboxylase ( porphyria cutanea tarda ) were measured in vitro in haemolysates and lymphoblasts of 10 subjects with dual porphyria in order to clarify the enzymatic defects .
