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 .
