Porphyria of doss or deficiency of delta-aminolevulinic acid dehydratase (DALAD) is an extremely rare form of acute hepatic porphyria (see this term) characterized by neuro-visceral attacks without cutaneous manifestations. Acute porphyria is a term that includes four similar inherited diseases: acute intermittent porphyria, variegate porphyria, hereditary coproporphyria, and ALAD deficiency porphyria. Overview. A fourth type, aminolevulinic acid dehydratase deficiency porphyria (ALAD), is an AR condition and is very rare. The rarest acute porphyria, which is caused by a defect in the enzyme ALA dehydratase, is known as delta-aminolevulinic aciduria or ALA dehydratase deficiency (ALAD) and has an autosomal recessive inheritance pattern.] This manual deals specifically with laboratory approaches to diagnosing inborn errors of metabolism. Very high levels of this compound can cause attacks of abdominal pain, vomiting, and other signs and symptoms of ALAD deficiency porphyria. These signs and symptoms can be life-threatening, especially if the muscles that control breathing become paralyzed. Please see the above notes on AIP and the acute porphyria FAQs . ALAD, ADP, Porphyria of Doss. Only four bona fide cases of Doss porphyria have been reported to date that were confirmed by immunological and molecular analyses of their ALAD mutations. Individuals with ALAD porphyria may have bouts or “attacks” when symptoms are intense, which are referred to as neurovisceral or acute attacks. Porphyria includes several subtypes, and each has unique manifestations, making an accurate diagnosis even more challenging The four types of acute hepatic porphyria (AHP) are acute intermittent porphyria (AIP), variegate porphyria (VP), hereditary coproporphyria (HCP), and ALAD-deficiency porphyria (ADP). ALAD-deficiency porphyria is the rarest form of acute porphyria with less than 10 cases reported in the literature to date (Doss et al., 1986, 2004; Akagi et al., 2006).

ADP is caused by a deficiency of the enzyme δ-aminolevulinic acid dehydratase (ALAD). (1991) studied 2 patients with homozygous ALAD deficiency: 1 had teenage onset of acute hepatic porphyria ( Doss et al., 1979 ); the second was a patient with late onset of the disease, a man who was 63 years old at the time of diagnosis ( Hassoun et al., 1989 ). Delta‐aminolevulinic acid dehydratase‐porphyria (ADP) is an autosomal recessive disorder of heme biosynthesis, caused by delta‐aminolevulinic acid dehydratase deficiency (ALAD).1 We report an important change in pathophysiological concepts and subsequent therapeutic options for patients with ADP, based on a review of previous cases and the treatment effects in a reported case.
