Of the An EGFR mutation (or biomarker) can negatively affect how the EGFR protein functions. Gene amplification and over-expression of the Erb family of receptors (EGFR and ErbB2) has been observed in breast, lung, and colorectal cancers, while the deregulated activation of intracellular mitogenic signaling has been implicated in many other cancers.
