【多选题】What are p orphyrias ?
A.
Porphyrias are a group of genetic diseases that result from defects in enzymes of the biosynthetic pathway from glycine to porphyrins; specific porphyrin precursors accumulate in erythrocytes, body fluids, and the liver.

C.
However, certain nutritional or environmental factors (as yet poorly understood) can cause a buildup of δ-aminolevulinate and porphobilinogen, leading to attacks of acute abdominal pain and neurological dysfunction.
D.
The symptoms of most porphyrias are now readily controlled with dietary changes or the administration of heme or heme derivatives.
