DCLK3 and neoplasm: Intriguingly, we identified a correlation between rs1800734 and DCLK3 expression in the healthy (P=0.029, linear regression model) and tumour (P=0.031, linear regression model) samples, and this association was highly significant in the MSS patients (P=0.004, linear regression model) (Fig. 2e), indicating this locus may act as a distal enhancer and regulate DCLK3.
