porphyria due to ALA dehydratase deficiency
A hepatic porphyria caused by biallelic variants in ALAD (in an autosomal recessive inheritance pattern). This is an extremely rare form of hepatic porphyria characterized by neuro-visceral attacks, nausea, vomiting, diarrhea, neuropathy, and abdominal pain without cutaneous manifestations. Because the disease is so rare, inducible triggers are not well-documented.
