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

In the present study, based in the Finnish population, we typed a large number of microsatellite markers in separately pooled DNA samples from 195 MS patients and 205 controls.

A total of 108 markers showed evidence of association.

Five genomic regions containing two or more of these markers within a 1-Mb interval were identified, 1q43, 2p16, 4p15, 4q34 and 6p21 (the MHC region).

Substantial overlap with previously published linkage genome screens is also seen.
