| basic personality type | An individual's unique, covert, or underlying personality propensities, whether or not they are behaviourally manifest or overt, personality characteristics of an individual which are also shared by a majority of the members of a social group. (05 Mar 2000) |
| Becker type muscular dystrophy | A muscular dystrophy that has many of the clinical features of Duchenne muscular dystrophy e.g., symmetrical involvement of first the pelvicrural muscles and then the pectoral girdle and proximal upper extremity muscles; pseudohypertrophy, especially of the calf muscles but with a much later age of onset (35-45 years), and more benign course. X-linked inheritance. (05 Mar 2000) |
| Becker type tardive muscular dystrophy | Muscular dystrophy of late onset, often in the second or third decade, with relatively mild course; X-linked recessive inheritance; perhaps allelic with Duchenne's dystrophy, but milder and not a genetic lethal. Compare: Duchenne dystrophy. Synonym: Becker type tardive muscular dystrophy. (05 Mar 2000) |
| blood type | The specific reaction pattern of erythrocytes of an individual to the antisera of one blood group; e.g., the ABO blood group consists of four major blood types: O, A, B, and AB. This classification depends on the presence or absence of two major antigens: A or B. Type O occurs when neither is present and type AB when both are present. The blood type is the genetic phenotype of the individual for one blood group system and may be determined using different antisera available for testing. See Blood Groups appendix. (05 Mar 2000) |
| Borst-Jadassohn type intraepidermal epithelioma | <tumour> Precancerous lesions clinically suggestive of actinic or seborrheic keratosis, with nests of immature or abnormal keratinocytes within the epidermis. (05 Mar 2000) |
| botulinum toxin type a | <chemical> A neurotoxin produced by clostridium botulinum. When consumed in contaminated food it can cause paralysis and death. In its purified form, it has been used in the treatment of blepharospasm and strabismus. Pharmacological action: neuromuscular agents. (12 Dec 1998) |

| gaucher's disease, type 1 | A progressive genetic disease caused by a defect in an enzyme. The enzyme, called glucocerebrosidase, is needed to break down the chemical glucocerebroside. The enzyme defect in persons with Gaucher's disease (GD) leads to the accumulation of glucocerebroside in the spleen, liver, and lymph nodes. The most common early sign is enlargement of the spleen (located in the upper left abdomen). Other signs include low red blood cell counts (anaemia), a decrease in blood clotting cells (platelets), increased pigmentation of the skin, and a yellow fatty spot on the white of the eye (a pinguecula). Severe bone involvement can lead to pain and collapse of the bone of the hips, shoulders, and spine. The GD gene is on chromosome 1. The disease is a recessive trait. Both parents carry a GD gene and transmit it for their child with the disease. The parents' risk of a child with the disease is 1 in 4 with each pregnancy. This type of Gaucher's disease (noncerebral juvenile Gaucher's disease) is most common in Ashkenazi Jews (of European origin) and is the most common genetic disease among Jews in the United States.

| mating type gene | Genes that, in Saccharomyces cerevisiae specify into which of the two mating types (a and _) a particular cell falls. Only unlike mating type haploids will fuse. The interest derives from the way in which mating type is switched, the existing gene is removed and a new gene, derived from a (silent) master copy elsewhere in the genome is spliced in. Later this gene will in its turn be replaced by a new copy of the old gene, also derived from a silent master. The a and _ genes code for pheromones that affect cells of the opposite mating type. Similar mating type genes are known from other yeasts and the switching mechanism (cassette mechanism) may be used more generally. (18 Nov 1997) |
| viral hepatitis type A | A virus disease with a short incubation period (usually 15 to 50 days), caused by hepatitis A virus, a member of the family Picornaviridae, often transmitted by faecal-oral route; may be inapparent, mild, severe, or occasionally fatal and occurs sporadically or in epidemics, commonly in school-age children and young adults; necrosis of periportal liver cells with lymphocytic and plasma cell infiltration is characteristic and jaundice is a common symptom. Synonym: epidemic hepatitis, hepatitis A, infectious hepatitis, MS-1 hepatitis, short incubation hepatitis, virus A hepatitis. (05 Mar 2000) |
