JCO Clinical Cancer Informatics doi: 10.1101/cshperspect.a020768. 2014 Jul 31;511(7511):543-50. doi: 10.1038/nature13385. All family members contain one or more repeats of the conserved amino acid sequence: Where C is cysteine, G is glycine, R is arginine, and X represents any amino acid. [14], This sequence contains six cysteine residues that form three intramolecular disulfide bonds. At least eight mutations in the EGFR gene have been associated with lung cancer. 2014 Oct 9;514(7521):262. Disulfide bond formation generates three structural loops that are essential for high-affinity binding between members of the EGF-family and their cell-surface receptors. Most of the somatic EGFR gene mutations that are associated with lung cancer delete genetic material in a part of the gene known as exon 19 or change DNA building blocks (nucleotides) in another region called exon 21. Thus, the systemic treatment of this disease remains unsatisfactory, and the need for more effective therapies is urgent. September 21, 2016.

Somatic EGFR gene mutations occur more frequently in Asian populations than in white populations, occurring in 30 to 40 percent of affected Asians compared to 10 to 15 percent of whites with lung cancer.

When these genetic changes occur in cells in the lungs, lung cancer can develop. This response may reflect the antitumor effect of ABX-EGF; however, a 6.6% response rate has been reported from a randomized trial of RCC patients with metastases without systemic treatment.15,16 Thus, the possibility of a spontaneous remission cannot be excluded. These gene changes result in a receptor protein that is constantly turned on (constitutively activated), even when it is not bound to a ligand. Epidermal growth factor (EGF) is a protein that stimulates cell growth and differentiation by binding to its receptor, EGFR. The EGFR gene provides instructions for making a receptor protein called the epidermal growth factor receptor, which spans the cell membrane so that one end of the protein remains inside the cell and the other end projects from the outer surface of the cell.
