It says there is a 1 in 750 chance of someone getting MS in the US.
It says there is a 1 in 40 chance of your child getting MS if a parent has MS.
When I was dx. in '92 the NMSS was saying there was a 1 in 1,000 chance of someone in the US of getting MS. They too said there was a 1 in 100 chance of passing MS to your kids. MS is on the increase and they don't understand why. The NMSS now says too it doesn't matter which parent has MS.
EDITED: to say I don't know if this has been brought up...I was going to double check and I accidentally hit the wrong key...
