| gastroenteritis virus type A | A RNA virus, about 27 nm in diameter, which has not been cultured in vitro; it is the cause of epidemic nonbacterial gastroenteritis; at least five antigenically distinct serotypes have been recognised, including the Norwalk agent. These viruses are probably classified with the Caliciviruses in the family Caliciviridae. Synonym: gastroenteritis virus type A. (05 Mar 2000) |
| gastroenteritis virus type B | <virology> Genus of the Reoviridae having a double layered capsid and 11 double stranded RNA molecules in the genome. They have a wheel like appearance in the electron microscope and cause acute diarrhoeal disease in their mammalian and avian hosts. Probably the most important cause of severe dehydrating diarrhoea in children under three years of age worldwide. Symptoms include nausea, vomiting, low-grade fever and diarrhoea. Aggressive fluid replacement is generally required. (27 Sep 1997) |
| 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) |
| viral hepatitis type B | A virus disease with a long incubation period (usually 50 to 160 days), caused by hepatitis B virus, a DNA virus and member of the family Hepadnoviridae, usually transmitted by injection of infected blood or blood derivatives or by use of contaminated needles, lancets, or other instruments; clinically and pathologically similar to viral hepatitis type A, but there is no cross-protective immunity; HBsAg is found in the serum and the hepatitis delta virus occurs in some patients. Synonym: hepatitis B, serum hepatitis, transfusion hepatitis, virus B hepatitis. (05 Mar 2000) |
| viral hepatitis type C | Principal cause of non-A, non-B posttransfusion hepatitis caused by an RNA virus that may be related to Flaviviridae family. Synonym: hepatitis C, virus C hepatitis. (05 Mar 2000) |
| viral hepatitis type D | Acute or chronic hepatitis caused by the hepatitis delta virus, a defective RNA virus requiring HBV for replication. The acute type occurs in two forms: 1) coinfection, the simultaneous occurrence of hepatitis B virus and hepatitis delta virus infections, which usually is self-limiting; 2) superinfection, the appearance of hepatitis delta virus infection in a hepatitis B virus carrier, which often leads to chronic hepatitis The chronic type appears to be more severe than other types of viral hepatitis. Synonym: delta hepatitis, hepatitis D. (05 Mar 2000) |
| viral hepatitis type E | Hepatitis caused by a nonenveloped, single-stranded, positive-sense RNA virus 27-34 nm in diameter, unrelated to other hepatitis; it is the principal cause of enterically transmitted, waterborne, epidemic NANB hepatitis occurring primarily in Asia and Africa. Synonym: hepatitis E. (05 Mar 2000) |
| central Recklinghausen's disease type II | type 1 neurofibromatosis |
| central type neurofibromatosis | Type I neurofibromatosis. Incomplete neurofibromatosis, multiple neurofibromas with minimal manifestations, perhaps limited to cafe-au-lait spots; individuals with minimal lesions may have offspring with severe involvement. Synonym: abortive neurofibromatosis. (05 Mar 2000) |
