Abstract excerpt
Multiple sclerosis (MS) is a complex trait with a sibling relative risk (lambda(sibs)) between 18 and 36. We report a multistage genome scan of 552 sibling pairs from 442 families, the largest MS family sample assessed for linkage. The first stage consisted of a genome scan for linkage with 498 microsatellite markers at an average spacing of 7 cM in 219 sibling pairs. The second stage involved further genotyping...
