| clonal deletion theory | The elimination of certain T-cell populations in the thymus that have receptors for self-antigens. See: immunologic tolerance. (05 Mar 2000) |
|---|---|
| point deletion | Deletion involving a submicroscopic loss of genetic material too small to be resolved by linkage analysis. Synonym: nucleotide deletion. (05 Mar 2000) |
| sequence deletion | Deletion of sequences of bases or amino acids from the genetic material of an individual. Evidence for these deletions may be obtained by cytological methods. (12 Dec 1998) |
| nucleotide deletion | Deletion of a single nucleotide, which in a transcribed gene will lead to a frameshift mutation. Synonym: point deletion. (05 Mar 2000) |
| deletion | <genetics> A chromosome abnormality in which part of a single chromosome has been lost. (13 Nov 1997) |
| deletion mutation | <molecular biology> A mutation in which one or more (sequential) nucleotides is lost by the genome. If the number lost is not divisible by 3 and is in a coding region, the result is a frameshift mutation. (18 Nov 1997) |
| interstitial deletion | Deletion that does not involve the terminal parts of a chromosome. (05 Mar 2000) |
| terminal deletion | Deletion involving the terminal part of a chromosome and leading to a adhesive terminus. (05 Mar 2000) |
