  • Repeat, Expanded Trinucleotide
  • Repeats, Expanded Trinucleotide
  • Trinucleotide Repeat, Expanded

Scope note

  • An increased number of contiguous trinucleotide repeats in the DNA sequence from one generation to the next. The presence of these regions is associated with diseases such as FRAGILE X SYNDROME and MYOTONIC DYSTROPHY. Some CHROMOSOME FRAGILE SITES are composed of sequences where trinucleotide repeat expansion occurs.
