| Type 1 GM1 gangliosidosis | One of the hereditary metabolic diseases of infancy; resembles Tay-Sachs disease, except other organ systems (bone, liver, kidney) are affected. Synonym: familial neuroviscerolipidosis, pseudo-Hurler disease, Type 1 GM1 gangliosidosis. (05 Mar 2000) |

| type 2 astrocyte | <pathology> A glial cell found in vertebrate brain, named for its characteristic star like shape. Astrocytes lend both mechanical and metabolic support for neurons, regulating the environment in which they function. See: oligodendrocytes. (18 Nov 1997) |
| type 2 dextrocardia | Dextrocardia with mirror transposition of the cardiac chambers but without displacement of the abdominal viscera. Synonym: type 2 dextrocardia. (05 Mar 2000) |
| type 2 diabetes | <endocrinology> Also referred to as adult-onset diabetes. More common in the middle-age, overweight individual. Usually treated by diet control, weight reduction or oral hypoglycemic agents. (27 Sep 1997) |
| type 2 glycogenosis | Glycogenosis due to lysosomal alpha-1,4-glucosidase deficiency, resulting in accumulation of excessive amounts of glycogen of normal chemical structure in heart, muscle, liver, and nervous system. Synonym: generalised glycogenosis, Pompe's disease. (05 Mar 2000) |
| type 3 dextrocardia | Displacement and rotation of the heart into the right side of the chest but without mirror transposition of the cardiac chambers. Synonym: dextroversion of the heart, false dextrocardia, type 3 dextrocardia. (05 Mar 2000) |
| type 3 glycogenosis | Glycogenosis due to amylo-1,6-glucosidase deficiency, resulting in accumulation of abnormal glycogen with short outer chains in liver and muscle. Synonym: Cori's disease, debranching deficiency limit dextrinosis, limit dextrinosis, Forbes' disease. (05 Mar 2000) |
| type 4 dextrocardia | Dextroposition of the heart by some disease of the lungs, pleura, or diaphragm. Synonym: type 4 dextrocardia. (05 Mar 2000) |
| type 4 glycogenosis | Familial cirrhosis of the liver with storage of abnormal glycogen; glycogenosis due to deficiency of 1,4-alpha-glucan branching enzyme, resulting in accumulation of abnormal glycogen with long inner and outer chains in liver, kidney, muscle, and other tissues. Synonym: Andersen's disease. (05 Mar 2000) |
| type 5 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) |
| type 6 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) |
| type 7 glycogenosis | Phosphofructokinase deficiency of muscle resulting in muscle cramps and myoglobinuria on extreme exertion. The clinical picture resembles type 5 glycogenosis. (05 Mar 2000) |
| type A behaviour | A behaviour pattern characterised by aggressiveness, ambitiousness, restlessness, and a strong sense of time urgency; associated with increased risk for coronary heart disease. (05 Mar 2000) |
| type a personality | Established behaviour pattern characterised by excessive drive and ambition, impatience, competitiveness, sense of time urgency, and poorly contained aggression. (12 Dec 1998) |
| type B behaviour | A behaviour pattern characterised by the absence or obverse of type A behaviour characteristics. (05 Mar 2000) |
