Analysis of the genetic mutations in the DNA-sequenced cohort of CRC patients from the TGCA database revealed that only 3.54% of patients with CRC bears a mutation in the KCNMA1 gene (http://www.cbioportal.org/)), including one case of in-frame deletion and nine cases of missense mutations, as shown in Table 1. Here, KCNMA1 is linked to colorectal carcinoma.
