The CTG repeat expansion size correlates with the splicing defects observed in muscles from myotonic dystrophy type 1 patients
8 Jul 2008
Abstract excerpt
BACKGROUND: Myotonic dystrophy type 1 is caused by an unstable (CTG)n repetition located in the 3'UTR of the DM protein kinase gene (DMPK). Untranslated expanded DMPK transcripts are retained in ribonuclear foci which sequester CUG-binding proteins essential for the maturation of pre-mRNAs. AIM: To investigate the effects of CTG expansion length on three molecular parameters associated with the DM1 muscle...
