Explanation

Acute intermittent porphyria (AIP) is characterized by abdominal pain, neuropsychiatric symptoms, and urine that darkens on standing due to porphobilinogen oxidation. Photosensitivity is NOT a feature of AIP - it occurs in cutaneous porphyrias like porphyria cutanea tarda and erythropoietic protoporphyria.
