Triplet repeat expansion in myotonic dystrophy alters the adjacent chromatin structure.
6 Jun 1995
Abstract excerpt
Myotonic dystrophy is caused by an expansion of a CTG triplet repeat sequence in the 3' noncoding region of a protein kinase gene, yet the mechanism by which the triplet repeat expansion causes disease remains unknown. This report demonstrates that a DNase I hypersensitive site is positioned 3' of the triplet repeat in the wild-type allele in both fibroblasts and skeletal muscle cells. In three unrelated...
