No linkage or association of the nitric oxide synthase genes to multiple sclerosis

J Neuroimmunol. 2001 Sep 3;119(1):95-100. doi: 10.1016/s0165-5728(01)00366-6.

Abstract

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) of unknown etiology. Nitric oxide (NO) is a free radical that participates in a variety of biological processes. It is an important mediator in the immune response. Several studies indicate involvement of NO in the pathogenesis of MS. We studied five markers within the three NO synthase genes with regards to susceptibility and disease course in 156 affected sib-pairs and in 96 "benign" and 96 "severe" definite MS patients and 148 controls. We found no significant association or evidence for linkage in our data sets.
