This is a multi-centre, case-controlled study to develop a dataset containing 1000 MS cases and 1000 matched controls and to associate DNA sequence (allelic) variations with MS phenotypes.
Study subjects were enrolled through a prospective effort initiated in 2003. Three MS clinical cent...
The goal of this study is to perform a comprehensive allelic and genotypic association analysis of t...
...nkage disequilibrium relationships among SNPs to further increase power (e.g. haplotype analysis). Quality control
and data analysis are significant challenges. We will initially perform substantial QC checks and analyze the data using both
TDT and AFBAC approaches. Multigenic interactions will also be tested using MDR.
