Multiple sclerosis (MS) is a demyelinating disorder of the central nervous system (CNS) with a complex genetic background.

Here we use a genome-wide association strategy with 4804 microsatellite markers successfully typed in separately pooled DNA from 200 patients and 200 controls.

A total of 91 markers showed evidence of association.

When compared to our in-house physical map of the genome, six 2-Mb regions containing at least two of these markers were detected.

Of those, three regions have one or more markers among the 20 most strongly associated: chromosomes 3q25, 6p21.3 (the MHC region) and 19q13.
