| 618892 | OMIM | Harderoporphyria (HARPO) | An autosomal recessive form of porphyria. Porphyrias are inherited defects in the biosynthesis of heme, resulting in the accumulation and increased excretion of porphyrins or porphyrin precursors. HARPO is a rare erythropoietic variant form characterized by neonatal hemolytic anemia, sometimes accompanied by skin lesions, and massive excretion of harderoporphyrin in feces. The disease is caused by variants affecting the gene represented in this entry. |
| 121300 | OMIM | Hereditary coproporphyria (HCP) | A form of porphyria. Porphyrias are inherited defects in the biosynthesis of heme, resulting in the accumulation and increased excretion of porphyrins or porphyrin precursors. They are classified as erythropoietic or hepatic, depending on whether the enzyme deficiency occurs in red blood cells or in the liver. Hereditary coproporphyria is an acute hepatic porphyria characterized by skin photosensitivity, attacks of abdominal pain, neurological disturbances, and psychiatric symptoms. Most attacks are precipitated by drugs, alcohol, caloric deprivation, infections, or endocrine factors. Hereditary coproporphyria is biochemically characterized by overexcretion of coproporphyrin III in the urine and in the feces. The disease is caused by variants affecting the gene represented in this entry. |
