| trinucleotide | A combination of three adjacent nucleotides, free or in a polynucleotide or nucleic acid molecule; often used with specific reference to the unit (codon or anticodon) specifying a particular amino acid in expression of the genetic code. (05 Mar 2000) |
|---|---|
| trinucleotide repeat | <molecular biology> Repetitive part of a genome that may form part of the coding sequence of a gene. The length of such repeats is frequently polymorphic and unstably amplified repeats appear to be the major cause of such genetic diseases as Huntington disease, fragile X syndrome, spinobulbar muscular atrophy and myotonic dystrophy. (18 Nov 1997) |
| trinucleotide repeats | Microsatellite tandem repeats (microsatellite repeats) consisting of three nucleotides dispersed in the euchromatic arms of chromosomes. (12 Dec 1998) |

| trinucleotide |
A three-base-pair portion of a gene that causes a specific amino acid to be put into the protein made by a gene. Also called a 'codon'. Huntington's Disease is caused by a trinucleotide repeat in the Huntington's gene that puts too many glutamine amino acids into the huntingtin protein made by the gene.

| trinucleotide |
Expansion of a segment of DNA within a gene that contains a repeat of three nucleotides (triplet repeats). This increase of triplet repeats happens as the gene is passed on from one generation to another. It can lead to abnormal gene expression and function. Triplet repeat diseases include fragile X syndrome, Huntington disease, myotonic dystrophy, and Friedreich ataxia.
