My mother and a cousing on my mother's side have multiple sclerosis. Am I likely to get MS?

My mother and a cousin on my mother's side have multiple sclerosis. Am I likely to get MS? I am 23 and planning to have a family and I would reconsider this if I had a high chance of developing the disease.

Some neurological disorders are inheirited, such as Huntington's disease and Duchenne muscular dystrophy. You do not get these disorders unless you have the appropriate genetic mutation. In other disorders, such as Parkinson's disease and motor neurone disease, a few patients have it as an inheirited disorder but most patients do not have a genetic abnomality. MS is different from both these groups. It is basically an immune disorder and while there is an inheirited susceptibility to MS, this is a not a major effect. I would consider that your risk of developing MS is quite small even with the positive family history. It would not be a sufficient risk to influence your decision to have children. At present, this is no test for susceptibility fo MS.
