Purpose of Study 

The purpose of the main study is to investigate adverse drug reactions from multiple sclerosis (MS) disease modifying drugs by understanding the genetic factors that contribute to their cause. 

The sub-study investigates how the MS disease modifying drugs affect microbes in the gut and how human DNA affects the changes in the gut microbes following drug treatment. We are also interested in how gut microbes might relate to progressive MS.
