Dynamic mutation: possible mechanisms and significance in human disease.

Abstract excerpt

Increases in repeat-DNA copy number are the molecular basis of a growing list of human genetic diseases, including fragile X syndrome, myotonic dystrophy, Huntington disease and a form of epilepsy. Repeat-DNA sequences undergo a unique process of dynamic mutation, the common properties of which probably reflect common molecular events. This form of mutation is no longer restricted to trinucleotide repeats,...
