In some lung cancer patients this gene, called EGFR, contains a DNA change known as an inherited EGFR mutation. Early data indicate that these inherited EGFR mutations may be associated with an increased risk of lung cancer. So far, only a small number of families have been found to carry inherited EGFR mutations. For this reason the risk of lung cancer associated with inherited EGFR mutations is not well understood.
Epidermal growth factor receptor (EGFR) is a transmembrane protein that is activated by binding of its specific ligands, including epidermal growth factor and transforming growth factor Î± (TGFÎ±) (note, a full list of the ligands able to activate EGFR and other members of the ErbB family is given in the ErbB article).
