Hi Vic. I am C9orf72 positive and my symptoms started just like you with right foot drop about 3 years ago. I now have both legs affected and pelvic muscles and am using a wheelchair. I'm trying a new cocktail of cheap available drugs based on my own research. Metformin is a MUST HAVE if you are C9. Laura Ranum's work is amazing and there is a trial ongoing in Florida. Also trying Terazosin and dutasteride. Vivienne
