CPOX-related hereditary coproporphyria
MONDO:0800180A porphyria caused by monoallelic and biallelic variants in CPOX and presenting as a spectrum of disease (a semidominant inheritance pattern). Monoallelic variants typically cause acute/episodic neurovisceral attacks with adolescent or adult onset, characterized by severe abdominal pain as well as acute motor neuropathy and other neurological symptoms. Triggers precipitating acute attacks include estrogen/progesterone, oral contraceptives, alcohol, drugs, stress, or infections. Cases with biallelic variants have symptoms in infancy, including hemolytic anemia, enlarged liver and spleen (hepatosplenomegaly), and severe jaundice. Additional symptoms may include erythrodontia, red urine, fragile skin, and cutaneous photosensitivity leading to scarring of sun-exposed skin.
