CHARACTERIZATION OF THE PORPHYRIAS Porphyrias are inherited disorders with defects in the enzymes of the heme In Dr. Thudichum published his first book on the analysis of urine which represents for that time the greatest chemical elaboration helping physicians to understand and diagnose many diseases including the porphyias.
The porphyrias are uncommon, complex, and fascinating metabolic conditions, caused by deﬁciencies in the activities of the enzymes of the haem biosynthetic pathway.
While most of them are inherited, some may also occur as acquired diseases. In addition, not all gene carriers of inherited porphyrias develop clinical disease and there is a. After researching the physicians' reports, Drs. Ida Macalpine and Richard Hunter proposed that King George might have had one of the acute porphyrias.
They published their theory in the British Medical Journal in and later wrote a book, George III and the Mad Business, which presented more detailed accounts of King George's malady.
The porphyrias are a group of different diseases, each caused by a specific abnormality in the heme production process. Heme is a chemical compound that contains iron and gives blood its red color.
The essential functions of heme depend on its ability to bind oxygen. Heme is incorporated into hemoglobin, a protein that enables red blood cells. The porphyrias are a group of disorders caused by defects in the synthesis of haem. A useful classification divides porphyrias into acute and non-acute: acute porphyrias present with abdominal pain and neuropsychiatric crises; non-acute prophyrias cause photosensitivity; The incidence of porphyria in the general population is aboutThe porphyrias are uncommon.
They are primarily hereditary disturbances in the synthesis of heme, involving well-defined enzymatic defects. Figure shows the process of heme synthesis involving multiple intermediates and at least eight enzymes. The inborn errors of heme biosynthesis, the porphyrias, are metabolic disorders, each resulting from the deficiency of a specific enzyme in the heme biosynthetic pathway (Figure 1; Table 1).
1,2 These enzyme deficiencies are inherited as autosomal dominant, autosomal recessive, or X-linked traits, with the exception of the most common porphyria, porphyria cutanea tarda (PCT), which usually.

Find definitive coverage of all aspects of liver disease in a new full-color format that keeps pace with your evolving practice. The porphyrias are inherited or acquired disorders in which the activity of an enzyme in the heme biosynthetic pathway is altered.
Metabolic intermediates are produced in excess, initially either in the marrow or the liver, and result in neurologic or photocutaneous symptoms and signs. Each of the eight enzymes involved in porphyrin synthesis can be defective and can produce a distinctive form of porphyria.
