Aminolevulinic acid dehydratase deficiency porphyria Aminolevulinic acid dehydratase deficiency porphyria Aminolevulinic acid dehydratase deficiency porphyria (also known as "Doss porphyria", and "plumboporphyria") is a neuropsychiatric condition, disease can present during early childhood (as well as in adulthood) with acute neurologic symptoms that resemble those encountered in acute intermittent porphyria. The condition is extremely rare, with fewer than 10 cases ever reported. ALA dehydratase deficiency is a rare cause of hepatic porphyria.

ALA dehydratase deficiency is inherited
