Copy number variation (CNV) is a structural variation in the human genome that has been associated with multiple clinical phenotypes. B cells are important components of rheumatoid arthritis- (RA-) mediated immune response; hence, CNV in the regulators of B cells (such as VPREB1) can influence RA susceptibility. In this study, we aimed to explore the association of CNV in the gene with RA susceptibility in the Pakistani population. A total of 1,106 subjects (616 RA cases, 490 healthy controls) were selected from three rheumatology
