title: A possible haplotype association in Felty's syndrome.
abstract: The HLA-B7/DR association was examined in a normal British population and in seven HLA-B7-positive patients with Felty's syndrome. After the exclusion of the most frequent A3-B7-DR2 association, a significant A2-B7-DR4 association was evident. This was present in six of the seven HLA-B7-positive Felty's patients and might indicate that the A2-B7-DR4 haplotype is prevalent in some forms of rheumatoid arthritis.
