    General Discussion
    ALA-D porphyria, a recently described form of acute porphyria, is inherited as an autosomal recessive trait and seems to be extremely rare. This form of porphyria is one of the hepatic porphyrias.

    The Porphyrias are a group of at least seven disorders. The common feature in all porphyrias is the excess accumulation in the body of porphyrins or porphyrin precursors. These are natural chemicals that normally do not accumulate in the body. Precisely which one of these porphyrin chemicals builds up depends upon the type of porphyria that a patient has.

    Porphyrias can also be classified into two groups: the hepatic and erythropoietic types. Porphyrins and related substances originate in excess amounts from the liver in the hepatic types, and mostly from the bone marrow in the erythropoietic types.

    The porphyrias with skin manifestations are sometimes called cutaneous porphyrias. The acute porphyrias are characterized by sudden attacks of pain and other neurological manifestations. These acute symptoms can be both rapidly-appearing and severe. An individual may be considered in a latent condition if he or she has the characteristic enzyme deficiency, but has never developed symptoms. There can be a wide spectrum of severity between the latent and active cases of any particular type of this disorder. The symptoms and treatments of the different types of porphyrias are not the same.
