IL6R and rheumatoid arthritis: For European populations, when colocalization analysis was conducted using plasma proteins from FinnGen sources and the RA data from Okada et al., four proteins (FCGR2A, FCRL3, IL6R and TGOLN2) exhibited high colocalization support (PH4 ≥ 0.8) and four proteins (EVI5, FCRL1, HLA-DRA and SWAP70) exhibited medium colocalization support (PH4 = 0.5 - 0.8) for RA.
