I dont think you can "pass on" the MS...I know that MS sometimes runs in families, but I dont think it's truly a genetic disease. There'd be more than 2 in my family if that were true. So far, the only MSers in my family are me, and a 2nd or 3rd cousin. (cant remember exactly where she is in the family tree...she's my dad's cousin's daughter...so, 3rd cousin??)

My family seems to have a lot of autoimmune diseases in it tho...on both sides. life threatening allergies, Rheumatoid arthritis, diabetes....

I probably have a bigger chance of passing down the birth defect that runs in my dad's family than I do of giving MS to any potential offspring. (I'd rather my potential kids got the birth defect than MS if they had to inherit something like that from me)
