Presentation

I have been working on the mechanisms of CTG.CAG repeat expansion in myotonic dystrophy (DM1) and Huntington diseases using different models.  In the team co-headed by G. Gourdon and D. Furling, we try to understand the mechanisms of CTG.CAG repeat contractions observed in atypical DM1 patients and DNA repair deficient cells.
