Epigenetics may reveal why MS genes are hard to find

I recent program presented on Nova described how twin women are the same and different. They both have the same base genetic information, and yet one has cancer and one does not. The cancer manifested through different environmental factors accumulating in Epigenetic proteins on top of the genetic information.

This seems like an excellent candidate research project for someone who happened to have a blood bank of people with MS and genetically related people without MS.
