Protective effect of the HLA-DRB1*13:02 allele in Japanese rheumatoid arthritis patients.
Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease. Certain HLA-DRB1 "shared-epitope" alleles are reported to be positively associated with increased RA susceptibility, whereas some of the other alleles may be negatively associated. However, studies on the latter are rare...
