While the frequencies of concomitant RAS mutations are similar to earlier studies in non‐BRAF V600E‐mutated CRC [38], we found that KRAS and NRAS co‐alterations were frequent in both BRAF class 2 and 3 mutated samples, and not confined to class 3 mutated samples [3, 37]. The gene discussed is KRAS; the disease is colorectal carcinoma.
