According to the following articles, four structure classes can be identified for EGFR mutations. Exon 18 mutations belong among PACC mutations which are most sensitive to second-generation TKIs (afatinib, dacomitinib, poziotinib, neratinib..).
Classifying EGFR mutations by structure and function offers better way to match non-small cell lung cancer patients to treatments https://www.mdanderson.org/newsroom/classifying-egfr-mutations-by-structure-and-function.h00-159464001.html
The articles are based on the following study:
