Association of HLA-DPB1 polymorphisms with rheumatoid arthritis: A systemic review and meta-analysis

This meta-analysis demonstrates that high frequency expression of DPB1*0401 and *0601 are significantly associated with susceptibility to RA, it may be a risk factor for occurrence of RA. Low frequency expression of DPB1*0101, *0402 and *0501 may be negatively associated with RA, it may be a protective factor for occurrence of RA.
