The immune-related pathways, ribosome pathway, immune-related genes including (HLA-DRB1, HLA-DPA1, HLA-DPB1, HLA-DOA and HLA-DRA) and ribosome-related genes (RPL31, RPS3A and RPL9) might be involved in systemic vasculitis.
The aim of this study was to examine the relationship between HLA-DP and susceptibility to articular and extra-articular features (Felty's syndrome and vasculitis) of rheumatoid arthritis (RA).
