| placental sulfatase deficiency | <enzyme> An enzyme defect in the placenta which results in failure of conversion of 16a-hydroxydehydroepiandrosterone to estriol; women with this condition rarely enter into spontaneous labour. (05 Mar 2000) |
|---|---|
| platelet storage pool deficiency | A group of disorders characterised by a decrease or lack of platelet dense bodies in which the releasable pool of adenine nucleotides and 5ht are normally stored. (12 Dec 1998) |
| congenital antithrombin III deficiency | Antithrombin III is a protein which stimulates the removal of blood clots in the bloodstream. Small blood clots form normally within the bloodstream, but are normally dissolved via the bodys antithrombin III. The deficiency of antithrombin III will result in an increased risk for blood clot formation causing organ damage. This is an inherited as a autosomal dominant trait. Inheritance: autosomal dominant. (27 Sep 1997) |
| multiple carboxylase deficiency | Abnormalities in carbohydrate and branched-chain amino acid catabolism that are responsive to biotin therapy. It may be due to deficiency of propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, biotinidase, or propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and pyruvate carboxylase. (12 Dec 1998) |
| congenital protein C or s deficiency | This inherited disorder of blood coagulation is characterised by a deficiency of vitamin K dependent plasma proteins (C and s) that are naturally occurring anticoagulants. This disorder results in an increased risk of blood clot formation within the circulatory system. (27 Sep 1997) |
| multiple sulfatase deficiency | An inherited disorder (autosomal recessive) in which there is a failure to hydrolyze sulfatides and sulfated mucopolysaccharides; this failure leads to their accumulation in neural and extraneural tissues causing demyelination, sulfatiduria, facial and skeletal dysmorphism, etc. (05 Mar 2000) |
| muscle phosphorylase deficiency | Type V glycogen storage disease, affecting muscle, caused by deficiency of muscle phosphorylase. (05 Mar 2000) |
| myophosphorylase deficiency glycogenosis | Glycogenosis due to muscle glycogen phosphorylase deficiency, resulting in accumulation of glycogen of normal chemical structure in muscle. Synonym: McArdle's disease, McArdle's syndrome, McArdle-Schmid-Pearson disease, myophosphorylase deficiency glycogenosis. (05 Mar 2000) |
| potassium deficiency | A condition due to decreased dietary intake of potassium, as in starvation or failure to administer in intravenous solutions, or to gastrointestinal loss in diarrhoea, chronic laxative abuse, vomiting, gastric suction, or bowel diversion. Severe potassium deficiency may produce muscular weakness and lead to paralysis and respiratory failure. Muscular malfunction may result in hypoventilation, paralytic ileus, hypotension, muscle twitches, tetany, and rhabomyolysis. Nephropathy from potassium deficit impairs the concentrating mechanism, producing polyuria and decreased maximal urinary concentrating ability with secondary polydipsia. (merck manual, 16th ed) (12 Dec 1998) |
| hageman factor deficiency | A deficiency of a specific blood clotting factor (XII) that may be genetic or acquired. Administration of heparin or severe liver disease may result in factor XII (Hageman factor) deficiency. There are usually no symptoms associated with this deficiency, but there may be symptoms of mild blood loss in some cases. Treatment is generally unnecessary. Individuals should be cautioned against the use of medications (for example aspirin, warfarin, heparin) with anticoagulant activity, due to risk of exaggerated effects. (27 Sep 1997) |
| hepatophosphorylase deficiency glycogenosis | Glycogenosis due to hepatic glycogen phosphorylase deficiency, resulting in accumulation of glycogen of normal chemical structure in liver and leukocytes. Synonym: hepatophosphorylase deficiency glycogenosis, Hers' disease. (05 Mar 2000) |
| protein c deficiency | Protein C is a protein in plasma that enters into the cascade of biochemical events leading to the formation of a clot. Deficiency of protein c results in thrombotic (clotting) disease and excess platelets with recurrent thrombophlebitis (inflammation of the vein that occurs when a clot forms). The clot can break loose and travel through the blood stream (thromboembolism) to the lungs causing a pulmonary embolism, brain causing a stroke (cerebrovascular accident), heart causing an early heart attack, skin causing what in the newborn is called neonatal purpura fulminans, the adrenal gland causing haemorrhage with abdominal pain, abnormally low blood pressure (hypotension), and salt loss. Protein c deficiency is due to possession of one gene (heterozygosity) in chromosome band 2q13-14. The possession of two such genes (homozygosity) is usually lethal. (12 Dec 1998) |
| protein deficiency | A nutritional condition produced by a deficiency of proteins in the diet, characterised by adaptive enzyme changes in the liver, increase in amino acid synthetases, and diminution of urea formation, thus conserving nitrogen and reducing its loss in the urine. Growth, immune response, repair, and production of enzymes and hormones are all impaired in severe protein deficiency. Protein deficiency may also arise in the face of adequate protein intake if the protein is of poor quality (i.e., the content of one or more amino acids is inadequate and thus becomes the limiting factor in protein utilization). (12 Dec 1998) |
| protein s deficiency | An autosomal dominant disorder showing decreased levels of plasma protein s antigen or activity, associated with venous thrombosis and pulmonary embolism. Protein s is a vitamin k-dependent plasma protein that inhibits blood clotting by serving as a cofactor for activated protein c (also a vitamin k-dependent protein), and the clinical manifestations of its deficiency are virtually identical to those of protein c deficiency. Treatment with heparin for acute thrombotic processes is usually followed by maintenance administration of coumarin drugs for the prevention of recurrent thrombosis. (12 Dec 1998) |
| prothrombin deficiency | A congenital or acquired disorder of blood clotting where there is a deficiency of factor II (prothrombin), one of 20 necessary plasma proteins for normal blood coagulation. Acquired factor II deficiency may result from vitamin K deficiency, severe liver disease and anticoagulant drugs. Symptoms include abnormal bleeding, nosebleeds, abnormal menstrual bleeding, easy bruising and umbilical cord bleeding at birth. Treatment involves the infusion of fresh frozen plasma. Vitamin K may be administered in select cases. (27 Sep 1997) |
