1Derived using founders from 720 trios (n=1,440 individuals).

2 P-value from allelic test of association using HAPLOVIEW (v.4.0).

3 P-value from allelic test of association using PDT (v.5.1); results based on the PDT-sum statistic. No significant results were observed for PDT-genotype tests of NOS2A SNPs (data not shown).

4 Families were considered DRB1*15 positive if the MS case carried at least one copy of DRB1*15. Families were considered DRB1*15 negative if the MS case carried no copies of DRB1*15. DRB1*15 carrier status was available for 1,114 of total 2,159 MS cases (51.9 %) included in this study. Medium-resolution typing of HLA-DRB1 (two to fourdigits) was performed (see Methods). A total of six of 1,045 MS cases withoutHLA-DRB1 genotype data were genotypedfor the rs3135388 (A/G) SNP to identify the MS-associated DRB1*15 allele, since the presence of thisallele and the rs3135388A SNP are highly correlated (see Methods).

5A total of 427 US families from the original study were included 20.

3 Families were considered DRB1*15 positive if the MS case carried at least one copy of DRB1*15. Families were considered DRB1*15 negative if the MS case carried no copies of DRB1*15. DRB1*15 carrier status was available for 1,114 of total 2,159 MS cases (51.9 %) included in this study. Medium-resolution typing of HLA-DRB1 (two to fourdigits) was performed (see Methods). A total of six of 1,045 MS cases withoutHLA-DRB1 genotype data were genotypedfor the rs3135388 (A/G) SNP to identify the MS-associated DRB1*15 allele, since the presence of thisallele and the rs3135388A SNP are highly correlated (see Methods). A total of 427 US families from the original study were included 20.

1Mild MS (N=104 MS cases) is defined as maintaining EDSS 3 after 15 years or more. Severe MS (N=101)

is defined as reaching EDSS >6 within 10 years.
