The underlying cause of all porphyrias is a defective enzyme important to the heme biosynthesis pathway. Porphyrias are inheritable conditions.
Hepatic porphyrias.
Its gravity.
All of the hepatic porphyrias--except porphyria cutanea tarda--follow a pattern of acute attacks separated by periods during which no symptoms are present.
The repetition in the poem Porphyrias Lover is "that moment she was mine, mine".
The erythropoietic porphyrias and porphyria cutanea tarda are considered to be chronic conditions.
the underlying cause is the main reason or motive for an action or event
The porphyrias are disorders in which the body produces too much porphyrin and insufficient heme (an iron-containing nonprotein portion of the hemoglobin molecule).
Erythropoietic porphyrias (erythropoiesis is the process through which red blood cells are produced).
A heart murmur is a symptom of an illness. You need to find the underlying cause. The underlying cause may cause death
Because heme is low, the synthesis path continues to produce precursor molecules. Each porphyria corresponds with an enzyme defect and an amassing of associated precursor.
