KDM2A and squamous cell carcinoma: DNA methylation at sites cg11637544 in KDM2A and cg26662347 in KDM1A were in the top 5% of VIS in both discovery phase and validation for squamous cell carcinomas (SCC), which were also significantly associated with SCC survival (HRcg11637544 = 1.32, 95%CI, 1.16–1.50, P = 1.1 × 10−4; HRcg26662347 = 1.88, 95%CI, 1.37–2.60, P = 3.7 × 10−3), and correlated with corresponding gene expression (cg11637544 for KDM2A, P = 1.3 × 10−10; cg26662347 for KDM1A P = 1.5 × 10−5).
