| recessive gene | A gene that is expressed onlywhen it is present in two copies or if theother copy is missing. (09 Oct 1997) |
|---|---|
| recessive inheritance | dominance of traits |
| recessive oncogene | <molecular biology> A single copy of this gene issufficient to suppress cell proliferation, the loss of both copies of the gene contributes to cancer formation. (09 Oct 1997) |
| recessive trait | See: dominance of traits. (05 Mar 2000) |
| recessive, x-linked | A gene on the X chromosome that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, duchenne muscular dystrophy (dmd) is an x-linked recessive disorder. A dmd boy has the dmd gene on his sole x chromosome (and so is said to be hemizgous for dmd). Although it is much rarer, a girl can have dmd (by several different means as, for example, if she has the dmd gene on both her x chromosomes and so is homozygous for dmd). (12 Dec 1998) |
| multiple intestinal polyposis | Begins usually in late childhood; polyps increase in numbers, causing symptoms of chronic colitis, and carcinoma of the colon almost invariably develops in untreated cases; autosomal dominant inheritance. In the Gardner syndrome there are extracolonic changes (desmoid tumours, etc.). Synonym: polyposis coli. Hamartomatous polyposis of the small or large intestine, Peutz-Jeghers syndrome with melanin spots on the lips, less common, miscellaneous, rare, and doubtful occurrences. Synonym: familial intestinal polyposis. (05 Mar 2000) |
| polyposis | Presence of several polyps. Origin: polyp + G. -osis, condition (05 Mar 2000) |
| polyposis coli | Hereditary disorder (Mendelian dominant) characterised by the development of hundreds of adenomatous polyps in the large intestine, which show a tendency to progress to malignancy. The APC gene has also been implicated in a chromosome 5 gastric and pancreatic cancer. (18 Nov 1997) |

| juvenile polyposis coli | <radiology> Benign polyposis, inheritance uncertain, inflammatory or retention polyps: round, smooth, soft, mucin-filled, non-neoplastic, onset less than 10 yrs, polyps can prolapse through anus, associated with diarrhoea, protein loss see: polyposis syndromes, Cronkhite-Canada syndrome (12 Dec 1998) |
| filiform polyposis | <radiology> Benign, non-specific sequela of diffuse, severe mucosal inflammation, UC, Crohn's, XR: thin, straight filling defects, resembles stalks of polyps without heads (12 Dec 1998) |

| arterial arches of colon | Anastomosing branches of the colic arteries that form arch's in the mesocolon from which the walls of the colon are supplied. See: marginal artery of colon. (05 Mar 2000) |
| ascending colon | <anatomy> The first part of the colon (large intestine) that starts in the right lower quadrant of the abdomen and ends at the transverse colon in the right upper quadrant of the abdomen. (27 Sep 1997) |
