The most significant positive correlations between the PKHD1L1 mRNA expression levels and patient survival rates were found in SKCM (log-rank p = 1.2 × 10−6) and LUAD (log-rank p = 1.3 × 10−3), while negative correlations were observed in kidney renal papillary cell carcinoma (KIRP), PAAD, and STAD (Figure 2, Supplementary Figure S2). The gene discussed is PKHD1L1; the disease is pancreatic adenocarcinoma.
