Effect of a genetic variant associated with Multiple Sclerosis mirrors response to anti-TNF therapy
Though anti-TNF therapy can be effective in the treatment of many auto-immune diseases including Rheumatoid Arthritis (RA), drugs that block TNF can promote or exacerbate Multiple Sclerosis (MS).
A genetic variant (rs1800693) within the TNFRSF1A gene has been identified in multiple GWAS as being associated with MS but not associated
