The SNP rs11102024 on 5′-upstream of CSF1 (colony-stimulating factor 1) gene encoding for M-CSF (macrophage colony-stimulating factor) on chromosome 1p13 showed significant association with AOSD (P = 3.70 × 10−7, OR (95% CI): 3.27 (2.07~5.17)) (Table 2). Here, CSF1 is linked to adult-onset Still disease.
