Rare should not mean alone
SCA12 is rare enough that many people are told very little at diagnosis, and rare enough that families often struggle to find each other. Cure SCA12 is run by people who have SCA12 themselves, and exists to close both of those gaps: to gather trustworthy information in one place, and to make sure nobody has to work it out on their own.
