AGAP2‐probe methylation seems to be positively correlated with AGAP2 expression in both lung tumour tissue from adenocarcinomas and squamous cell carcinomas (Pearson's correlation coefficient = 0.49, p value 0.025; and Pearson's correlation coefficient = 0.55, p value = 0.15 respectively). Here, AGAP2 is linked to adenocarcinoma.
