SAMD1 and neoplasm: From TCGA tumor expression data via GEPIA2, the top 100 genes positively correlated with LRFN4 expression were determined, among which TPX2 (R = 0.36), KIF18B (R = 0.39), RCE1 (R = 0.53), PCNXL3 (R = 0.49), and SAMD1 (R = 0.48) showed significant correlations (P < 0.001) (Figure 14D).
