To investigate the immunoediting role of ADAR in gastric cancer further, we queried the iAtlas portal57, where CNVs on ADAR were reported to exhibit high effect sizes on Leukocyte Fraction (Amp: p = 10−4 to 10−10 (multiple groups)), Lymphocyte Infiltration Score, (Amp: p = 10−6/Del: p = 10−5), and CD8+ T Cell content (Del: p = 10−4). The gene discussed is ADAR; the disease is gastric cancer.
