Definition
English
:
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.
