Article abstract-We assessed the influence of human leukocyte antigen (HLA) class II as susceptibility genes in multiple sclerosis (MS) by linkage analysis. Other research groups, who have shown negative results in studies on affected sibling pairs, have questioned the influence of the HLA class II genes, although they confirmed the association of the DR15,DQ6,Dw2 haplotype to MS. In this report, we find a significant lod score (>3) when using a 2-point linkage analysis of 49 small Swedish nuclear MS families with at least two affected family members, typed for HLA class II alleles by PCR amplification with sequence-specific primers. We obtained maximum lod scores when we used dominant or intermediate models with low penetrance. We found that the positive effect on the total lod score was not confined to those families carrying the presumed susceptibility HLA-haplotype Dw2. This observation supports the notion of a functional role of the HLA class II molecules themselves in MS. In addition, we observed significant transmission distortion and an intrafamilial association of the MS-associated class II haplotype HLA-Dw2. These results indicate that the HLA class II genes are of clear importance for MS in the studied population.NEUROLOGY 1997;48: 758-762
