After years of seeing reports of no genetic markers found or genetic ties it sounds like this is being looked into. I can’t think of any of my relatives with MS but in this group there are constant references to a grandpa that had it or cousins, etc. For a disease that is relatively rare it seem like there are too many mentions of close family members that they know that have MS.
In my case my mom was bi-polar and in her 60’s developed a condition similar to parkinsons but not exactly that. Her mother had multi-in farc dementia. Not MS but maybe someday they will find some linkages.
Just thought I’d toss this out there in case others hadn’t see the info: https://www.healthline.com/health-news/new-research-indicates-ms-may-be-genetic-in-some-families?slot_pos=article_2&utm_source=Sailthru%20Email&utm_medium=Email&utm_campaign=multiplesclerosis&utm_content=2019-10-03&apid=29101565
