Somatic mutations in BRAF have been found in 1-4% of all NSCLC most of which are adenocarcinomas. The G466R mutation results in an amino acid substitution within the kinase domain of BRAF. Unlike other mutant BRAF proteins, G466R shows decreased kinase activity, however, it also causes paradoxically activation Erk signaling in cell culture Therapeutic implications of BRAF inhibitors in patients with this mutation need to be fully elucidated.
