ferrochelatase
porphobilinogen deaminase
aminolevulinic acid synthase
uroporphyrinogen decarboxylase
aminolevulinic acid dehydratase

aminolevulinic acid synthase
→ sideroblastic anemia

aminolevulinic acid dehydratase
→ lead poinsoning, ALA accumulate

☆porphobilinogen deaminase
→ acute intermittent porphyria, ALA, porphobilinogen accumulate

uroporphyrinogen decarboxylase
→ porphyria cutanea tarda, uroporphyrin accumulate

ferrochelatase
→ lead poinsoning, protoporphyrin accumulate
