Why More Women Get Multiple Sclerosis
Heh, genetic variations. No surprise.
- The international team studied the genes of MS patients in the U.S. They also looked at gene patterns in people from Northern Ireland and Belgium, some of whom had MS.
Women with MS were more likely to have a variation of a gene that produces high levels of a protein called interferon gamma. Interferon gamma can aggravate MS by promoting inflammation and tissue damage.
In the U.S. and Northern Ireland, men with the gene variation were more susceptible to MS. That was also true for Belgian men, but the effect wasn't significant there.
