Additionally, three new genomic associations with giant cell arteritis were identified at the 8p21.1 (CCDC25, rs11782624; p=1·28 × 10–8; OR 1·18 [95% CI 1·12–1·25]), 15q26.1 (MFGE8, rs8029053; p=4·96 × 10–8; OR 1·19 [1·12–1·26]) and 17q11.2 (VTN, rs704; p=2·75 × 10–9; OR 0·84 [0·79–0·89]) regions. This evidence concerns the gene MFGE8 and arteritis.
