In 212 patients with RAS wild type, BRAF mutation was found significantly related to older age (9.5% in patients aged≥65y vs. 2.2% in patients aged<65y, p=0.017) and female patients (9.2% in female patients vs. 2.2% in male patients, p=0.021), and the BRAF mutation was higher (approaching significance) in right-sided CRC than left-sided CRC (10.5% vs. 3.4%, p=0.062). This evidence concerns the gene BRAF and colorectal carcinoma.
