I just got my packet for the Multiple Sclerosis Genetic Susceptibility Project that the researchers at the University of California at San Francisco is doing. I was wondering if anyone else is participating in this.

All it entails is giving a blood sample. But, I am wondering if a family member (parent, sibling, etc.) would need to participate. I spoke to my parents and both are willing to participate. Does anyone know if this is the study that involves family members?
