Porphyrin Heme B group of hemoglobin. An iron (Fe) atom in the middle is shown in red, complexed to four interior nitrogen atoms shown in blue. Porphyrins are a group of heterocyclic macrocycle organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges (=CH−). The parent porphyrin is porphin, and substituted porphines are called porphyrins.

Platelet Disorders Adhesion Disorders. An adhesion disorder is the result of the platelets not being able to stick to the wall of the damaged blood vessel to form a plug and stop the bleeding.

Porphyria Other types of porphyria, called acute porphyrias, primarily affect the nervous system. These disorders are described as acute because their signs and symptoms appear quickly and usually last a short time. Episodes of acute porphyria can cause abdominal pain, vomiting, constipation, and diarrhea.

Homocystinuria Homocystinuria is an autosomal recessive inherited metabolic disorder caused by a defect in an enzyme that converts the amino acid homocysteine to cystathionine, resulting in accumulation of homocysteine in the blood and its excretion in urine.

Thyroid function tests Thyroid function tests are used to tell whether your thyroid is working normally. The most common thyroid function tests are: 1  Total, or free T4 (the main thyroid hormone in your blood). 2  TSH (the hormone from the pituitary gland that stimulates the thyroid to produce T4). 3  T3 (also included sometimes).

15 Signs You May Have a Thyroid Problem (With hyperthyroidism, you may also have nighttime insomnia that leaves you exhausted during the day.) Fatigue symptoms are usually mild at first before increasing in intensity. The key identifier of thyroid-related fatigue is that is remains unrelieved, no matter how much you sleep or nap during the day. This fatigue inhibits patients’ ability to remain productive in day-to-day life, and it’s often what causes them to see a doctor for a diagnosis.

Coagulopathy Coagulopathy (also called a clotting disorder) is a condition in which the blood’s ability to coagulate (form clots) is impaired.oagulopathy may be caused by reduced levels or absence of blood-clotting proteins, known as clotting factors or coagulation factors. Genetic disorders, such as hemophilia and Von Willebrand's disease, can cause a reduction in clotting factors.

Hepatic porphyria Hepatic porphyria. Hepatic porphyrias is a form of porphyria in which the enzyme deficiency occurs in the liver. Examples include (in order of synthesis pathway): Acute intermittent porphyria. Porphyria cutanea tarda and Hepatoerythropoietic porphyria.

Platelet Disorders An aggregation disorder is when platelets do not bind with fibrinogen and other proteins in order to stick to other platelets. As a result the platelets cannot form a plug to stop the bleeding from a damaged blood vessel.

Porphyria Porphyria is a group of diseases that are due to the deficiency of one of the enzymes needed to make an important substance in the body called heme. Porphyrias are often classified as acute or cutaneous. Acute types of porphyria affect the nervous system, whereas cutaneous types mainly affect the skin.

Variegate porphyria Some types of porphyria are inherited in an autosomal dominant pattern, which means one copy of the gene in each cell is mutated. This single mutation is sufficient to reduce the activity of an enzyme needed for heme production, which increases the risk of developing signs and symptoms of porphyria.n males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes the disorder. Males may experience more severe symptoms of the disorder than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

10 Aug What Is Porokeratosis? Porokeratosis is a disorder of keratinization or a skin disorder. The disease is widely known as a hereditary dermatitis; it runs down a family related line. Its main characteristic is the spreading of lesions on the body.The disease can affect any part of the body, and it mostly affects the adults.inear Porokeratosis. It is also a rare disease as it is also listed as a rare disease but affects both male and female. The skin disorder is characterized by papules and plaques on the body which form a linear pattern.

Bleeding Disorders What Is a Bleeding Disorder? A bleeding disorder is a condition that affects the way your blood normally clots. The clotting process, also known as coagulation, changes blood from a liquid to a solid. When you’re injured, your blood normally begins to clot to prevent a massive loss of blood. Sometimes, certain conditions prevent blood from clotting properly, which can result in heavy or prolonged bleeding.

- The symptoms of erythropoietic protoporphyria develop due to excessive levels of a chemical called protoporphyrin that accumulates in certain tissues of the body (i.e., the plasma, red blood cells, and the liver).

Porphyria Porphyria results from accumulation of porphyrins either in the skin, which results in sensitivity to sunlight, or in the liver, which results in acute attacks of porphyria.cute intermittent porphyria. The next most common form of porphyria is acute intermittent porphyria or AIP. AIP causes only neurological symptoms and does not affect the skin. AIP is inherited but may appear to skip generations as many people who inherit the disease never get any symptoms.

Acute intermittent porphyria Acute intermittent porphyria: Introduction. Acute intermittent porphyria: A rare metabolic disorder characterized by a deficiency in the porphobilinogen deaminase enzyme which results in a build-up of porphyrins or its precursors in the body. Using certain drugs or eating certain foods can trigger the symptoms of the condition.

Acute Intermittent Porphyria (AIP) General Discussion. Acute intermittent porphyria (AIP) is a rare metabolic disorder that is characterized by deficiency of the enzyme as hydroxymethylbilane synthase (also known as porphobilinogen deaminase). This enzyme deficiency can result in the accumulation of porphyrin precursors in the body.
