PG - 12-3 AB - Analysis of individual human leukocyte antigen (HLA) genes associated with rheumatoid arthritis was performed using oligonucleotide probes to identify putative susceptibility genes highly associated with disease. Among DR4-positive rheumatoid arthritis patients, two distinct DR-beta genes, Dw4 and Dw14, appear to be individual susceptibility alleles. Linked HLA genes at the DQ locus do not appear to contribute to this genetic risk. Among non-DR4 rheumatoid arthritis patients, a specific DNA sequence was identified that is shared by the Dw14 susceptibility gene and a majority of the non-DR4 rheumatoid arthritis patients. This sequence defines a specific small genetic element encoding a "Dw14 epitope" that appears to be a rheumatoid arthritis-associated risk factor indicative of a common genetic pathway in both DR4 and non-DR4-associated disease.
