To analyze the effects of somatic cell copy number alternations (CNAs) of these two genes on infiltration of immune cells, such as B, CD4+ T, CD8+ T, dendritic cells, neutrophils, and macrophages, we applied the Tumor Immune Estimation Resource (TIMER, https://cistrome.shinyapps.io/timer/). The gene discussed is CD8A; the disease is neoplasm.
