ANCHOR LEAD: MORE GENES RELATED TO MS HAVE BEEN FOUND, ELIZABETH TRACEY REPORTS
More genes related to multiple sclerosis have been identified. But Peter Calabresi, an MS expert at Johns Hopkins, cautions that finding genes doesn’t mean that MS is necessarily inherited.
CCALABRESI: I want to clarify that it’s not a gene, so some people suddenly decide that if they have MS, suddenly their kids are at risk for MS and it’s a fifty percent risk, and it’s not like that at all, what we’re finding is that there are genes that predispose people and there are going to be other ones and there will be different patterns in different types of MS patients. I want to make sure that people don’t come away thinking that these are the genes that cause MS. They’re just contributing. :26
Genes can change, or mutate, over someone’s lifetime and give rise to conditions like MS, but such changes are not passed on to one’s children the way characteristics like eye color are. I’m Elizabeth Tracey reporting.
