My brother had MS died of MS complications. He refused to get a feeding tube; he had lived with the MS sh*t long enough. His son has MS and now we have learned my son has MS. The primary progressive type. I watched my brother die, it terrifies me that I will have to watch my son go through the same. My son is pretty much bed bound, in pain, and mad at the world. If my family has the genes that pass MS on, it must pass through the male gene. My kids just had baby boys, 4 of them. I probably won't be alive to see which one of them will get MS. Can the 200 genes that contributes to MS be identified?
