We have compared haplotypes bearing HLA-A, -B, -DR; Bf and C4 genes in 54 rheumatoid arthritis (RA) and 24 control families. There was no statistically significant differences in C4A or C4B gene frequencies between RA and control groups, although there were trends for C4B*Q0 to be reduced and C4B2 to be increased in DR4 positive RA compared with DR4 positive controls. The lack of any strong association between C4 variants and RA overall makes it unlikely that the association between RA and genes within the MHS represents a direct effect of variants within the C4A or C4B loci themselves. On comparison of DR4-bearing haplotypes, the haplotype B15-BfS-DR4 was increased fourfold and the B44-Bfs-DR4 haplotype was less frequent in the RA group. When C4 variants were also considered, the haplotype B44-C4B*Q0-C4A3-BfS-DR4 was nine times less frequent in RA patients than in controls. The observation that different DR4 bearing haplotypes may confer either increased or decreased susceptibility to RA suggests either that it is unlikely that DR4 itself is involved in the disease process or that specific haplotypic combinations are important. Thirty-two RA patients were HLA-DR4 negative. No single DR4 negative haplotype was found to confer significantly increased susceptibility to RA.
