We identified rs7515174 (G-allele, allele frequency = 11.2%) as an intronic cis-pQTL unique to FCGR2A measured by Olink (beta = −1.25, p value < 7.5 × 10−41) and a shared signal with rheumatoid arthritis (RA) in Europeans31 (beta = −0.11, PP > 84.9%). Here, FCGR2A is linked to rheumatoid arthritis.
