| type | 1. The mark or impression of something; stamp; impressed sign; emblem. 2. Form or character impressed; style; semblance. 3. A figure or representation of something to come; a token; a sign; a symbol; correlative to antitype. 4. That which possesses or exemplifies characteristic qualities; the representative. <biology> Specifically: A general form or structure common to a number of individuals; hence, the ideal representation of a species, genus, or other group, combining the essential characteristics; an animal or plant possessing or exemplifying the essential characteristics of a species, genus, or other group. Also, a group or division of animals having a certain typical or characteristic structure of body maintained within the group. <chemistry> A simple compound, used as a mode or pattern to which other compounds are conveniently regarded as being related, and from which they may be actually or theoretically derived. The fundamental types used to express the simplest and most essential chemical relations are hydrochloric acid, HCl; water, H2O; ammonia, NH3; and methane, CH4. 5. A raised letter, figure, accent, or other character, cast in metal or cut in wood, used in printing. Such letters or characters, in general, or the whole quantity of them used in printing, spoken of collectively; any number or mass of such letters or characters, however disposed. Origin: F. Type; cf. It. Tipo, from L. Typus a figure, image, a form, type, character, Gr. The mark of a blow, impression, form of character, model, from the root of to beat, strike; cf. Skr. Tup to hurt.

|---|---|
| type 1 dextrocardia | Displacement of the heart to the right side of the chest with mirror transposition of the cardiac chambers together with transposition of the abdominal viscera. Synonym: type 1 dextrocardia. (05 Mar 2000) |
| type 1 diabetes | <endocrinology> Also referred to as juvenile onset diabetes. Underlying cause is likely genetic. Usually treated with daily insulin dosing. Insulin is necessary for the body to properly utilise glucose. Without insulin, glucose accumulates in the bloodstream. (27 Sep 1997) |
| type 1 glycogenosis | Glycogenosis due to glucose-6-phosphatase deficiency, resulting in accumulation of excessive amounts of glycogen of normal chemical structure, particularly in liver and kidney. Synonym: Gierke's disease, glucose-6-phosphatase hepatorenal glycogenosis, von Gierke's disease. (05 Mar 2000) |
| 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) |
