| tumor marker | <investigation, oncology> A substance in the body that usually indicates the presence of cancer. These markers are usually specific to certain types of cancer and are usually found in the blood or other tissue samples. Examples are alphafetoprotein (AFP), human chorionic gonadotropin, and lactate dehydrogenase (LDH). They may be indicators of tumour stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including hormones, antigens, amino and nucleic acids, enzymes, polyamines, and specific cell membrane proteins and lipids. (18 Jul 2002) |

| linkage marker | A locus at which there is a high probability of heterozygotes (indispensible state for linkage analysis), but in itself perhaps of no clinical interest. See: marker locus. (05 Mar 2000) |
| genetic locus | <genetics> The position of a gene in a linkage map or on a chromosome. (18 Nov 1997) |
| cis-acting locus | A section of DNA that affects the activity of DNA sequences on that same molecule of DNA. (05 Mar 2000) |
| complex locus | A set of closely linked genetic loci with a common function, as in the major histocompatibility complex locus. (05 Mar 2000) |
| W locus | <molecular biology> Mouse coat colour locus, equivalent to the kit proto-oncogene, that encodes a receptor tyrosine kinase essential for development of haemopoietic and germ cells. (18 Nov 1997) |
| multi locus enzyme electrophoresis | Inhibition of translation of the transcript of a transposase gene by a multicopy plasmid with suitable inhibitory gene. The plasmid inhibits transposition events in the host bacterium. (18 Nov 1997) |
| multi-locus probe | A probe that hybridizes to anumber of different sites in the genome of an organism. (09 Oct 1997) |
| X-linked locus | Any locus that in normal karyotypes is borne on the X chromosome. (05 Mar 2000) |
| sex-linked locus | Any locus that in normal karyotypes is borne on a heterosome; commonly but incorrectly applied to an X-linked locus. (05 Mar 2000) |
| Y-linked locus | Any (haploid) locus that in normal karyotypes is borne on the Y chromosome. The known content is so far small. (05 Mar 2000) |
| locus | <genetics> The site in a linkage map or on a chromosome where the gene for a particular trait is located. Any one of the alleles of a gene may be present at this site. (18 Nov 1997) |
| locus ceruleus | A shallow depression, of a blue colour in the fresh brain, lying laterally in the most rostral portion of the rhomboidal fossa near the cerebral aqueduct; it lies near the lateral wall of the fourth ventricle and consists of about 20,000 melanin-pigmented neuronal cell bodies whose norepinephrine-containing axons have a remarkably wide distribution in the cerebellum as well as in the hypothalamus and cerebral cortex. Synonym: substantia ferruginea, locus cinereus, locus ferrugineus. (05 Mar 2000) |
