| unstable mutation | <molecular biology> A mutation that has a high likelihood of reverting to its original form. (13 Nov 1997) |

| angina, unstable | Precordial pain at rest, which may precede a myocardial infarction. (12 Dec 1998) |
|---|---|
| DNA sequence, unstable | DNA region comprised of a variable number of repetitive, contiguous trinucleotide sequences. Presence of these regions is associated with diseases such as fragile x syndrome and myotonia atrophica. (12 Dec 1998) |
| unstable angina | <cardiology> Angina which is new onset or prior existing angina which is increasing in severity, duration or frequency. (13 Nov 1997) |
| unstable bladder | Characterised by uninhibited detrusor contractions. (05 Mar 2000) |
| unstable cervical spine fractures | <radiology> Flexion: bilateral interfacetal dislocation, flexion teardrop fracture (usually C5 or C6) extension: extension teardrop fracture (usually C2 or C3), hangman's fracture, extension-dislocation, extension-fracture-dislocation, odontoid fracture vertical compression: Jefferson burst fracture see: cervical spine fractures (12 Dec 1998) |
| unstable colloid | A colloid that is not again soluble in water after having been dried at ordinary temperature. Synonym: unstable colloid. (05 Mar 2000) |
| unstable fracture | A fracture with an intrinsic tendency to slip out of place after reduction. (05 Mar 2000) |
| unstable haemoglobin haemolytic anaemia | A congenital haemolytic anaemia, due to autosomal inheritance of one of many unstable haemoglobins. The anaemia is of variable severity and characterised by the presence in vivo or in vitro of Heinz bodies. (05 Mar 2000) |
| unstable haemoglobins | A group of rare Hb's with amino acid substitutions (or amino acid deletions in three types) that alter the three-dimensional shape of the globin in a manner that renders the molecule unstable; they have an increased but variable tendency to auto-oxidation and Heinz body formation and are associated with congenital nonspherocytic haemolytic anaemia. The unstable b chain abnormalities include Hb's Genova, Gun Hill, Hammersmith, Koln, Philly, Sabine, Santa Ana, Sydney, Wien, and Zurich; unstable a chain abnormalities include Hb's Bibba, Sinai, and Torino. (05 Mar 2000) |
| unstable patient | The distinction of stability is made by a physician and based on a large number of variables: patient diagnosis, vital signs, physical findings, laboratory findings, subjective factors and patient prognosis. (27 Sep 1997) |
| acquired mutation | A change in a gene or chromosome that occurs in a single cell after the conception of the individual. That change is then passed along to all cells descended from that cell. Acquired mutations are involved in the development of cancer. (12 Dec 1998) |
| addition-deletion mutation | <molecular biology> A type of mutation that results from insertion or deletion of a single nucleotide into, or from, an open reading frame in the normal DNA sequence. Normally, the genetic code is read in the wrong frame, three nucleotides at a time, and the entire sequence downstream of the mutation, is translated into a polypeptide with a garbled amino acid sequence from the mutated codon onwards. These mutations may be induced by certain types of mutagens or may occur spontaneously and usually result in the generation, downstream, of nonsense, chain termination codons. Synonym: addition mutation, addition-deletion mutation, deletion mutation, reading-frameshift mutation. (21 Jun 2000) |

| amber mutation | <molecular biology> A mutation from a codon which codes for an amino acid into the amber codon UAG, which normally signals that the translation of mRNA into an amino acid chain should stop. The mutation causes the amino acid chain to stop forming before it is actually completed. (09 Oct 1997) |
| back mutation | <molecular biology> A mutation that causes a mutant gene to revert to its original wild-type base sequence. Compare: forward mutation. (09 Oct 1997) |
