For instance, in BLCA, we observed correlations between PDCD1 CNVs and CD8 naive immune filtrates (Corr = −0.17, p = 5.16 × 10−4, FDR = 6.03 × 10−3), NK (Corr = 0.18, p = 2.35 × 10−4, FDR = 3.4 × 10−3), as well as CXCL13 CNVs with macrophages (Corr = −0.22, p = 3.69 × 10−6, FDR = 9.37 × 10−5). The gene discussed is CXCL13; the disease is bladder transitional cell carcinoma.
