Extended haplotypes of chromosome 6 in adult rheumatoid arthritis.

In 46 patients with rheumatoid arthritis (RA) the allele C4B*3 occurred in 6 patients, while among 350 normal controls, it occurred 6 times (P less than 0.00002). Among 9 white and 1 black families, each of which had 2 or more members with RA, there were 36 haplotypes associated with RA. An extended haplotype (specific HLA-B, DR, complotype haplotypes in significant linkage disequilibrium) containing C4B*3: HLA-B15, DR4, BF*S, C2*C, C4A*3, C4B*3, was found twice (P less than 0.001) among whites with the disease-associated chromosomes.

Study of HLA antigens in familial and sporadic rheumatoid arthritis.

Patients with familial and non-familial (sporadic) forms of rheumatoid arthritis (RA) were studied to investigate possible HLA heterogeneity. HLA-DR4 was present in 75% of familial and 59% of sporadic RA patients. The frequency distribution of A2, B8, B27, Cw3 and DR3 differed somewhat between the two groups; however, the differences were not statistically significant in this small group of patients. Studies of a larger number of patients are indicated to explore the possibility of genetic subgroups in RA.
