The BRAF mutation is known to be mutually exclusive with KRAS and/or NRAS mutations in other cancers [21]; however, in our study, mutations in BRAF did not appear to be exclusive to either the KRAS or NRAS mutation because mutations in KRAS, NRAS, and BRAF were all found in the same patient (patient #1, Table 3). Here, KRAS is linked to cancer.
