CDCA4 and colorectal carcinoma: By extracting variant information for CDCA4 from the transcriptomic data of 36 non-PCR and 18 PCR CRC patients prior to chemoradiotherapy, we observed that the mutation frequency of CDCA4 in the PCR group was significantly higher than that in the non-PCR group (Chi-square test, p = 0.03) (Figure 3E).
