The following ERBB2 KD mutants are resistant to lapatinib:
ERBB2 L755P (Kancha et al. 2011; Yang et al. 2015 - the L755P substitution results in a structural change that makes binding to lapatinib energetically unfavorable; Nagano et al. 2018);
ERBB2 L755S (Kancha et al. 2011, Bose et al. 2013, Cocco et al. 2018, Nagano et al. 2018);
ERBB2 D769Y (Bose et al. 2013; partial sensitivity reported by Nagano et al. 2018);
ERBB2 T798I (Trowe et al. 2008);
ERBB2 T798M (Kancha et al. 2011, Rexer et al. 2013, Hanker et al. 2017);
ERBB2 T733I (Trowe et al. 2008);
ERBB2 V842I (Bose et al. 2013, Nagano et al. 2018);
ERBB2 L869R (Hanker et al. 2017);
One study reported sensitivity of ERBB2 I767M, ERBB2 P780_Y781insGSP and ERBB2 R896C to lapatinib (Nagano et al. 2018), while another study reported resistance (Bose et al. 2013).
