Now the University of British Columbia geneticist spends her time studying the disease. "My involvement with MS has gone back since before I was born, and it seemed like a natural evolution to just go on and study MS as I got older." Ms. Sadovnick spoke of the connection between genetics and multiple sclerosis at the MS research luncheon Thursday in Halifax. Multiple sclerosis recurs more often in families than in the general population, her study found. If a sibling has multiple sclerosis, you are 15 to 25 times more likely to develop it yourself. Identical twins have identical DNA. There is a 34 per cent chance both twins will develop multiple sclerosis, according to the study. But there is only a 5.2 per cent chance that both fraternal twins — who only share half their DNA — will get the disease.....more |
