Question: what are the chances of getting ms if your mother has it?
Answer: "If a mom or dad has MS, their children have between a 5 and 10 percent chance of getting it," Dr. Rose says. The MS risk is 1 in 750 for most people, 1 in 40 for those with close family members with the disease and 1 in 4 for those with an identical twin who has it.
