ERBB2 kinase domain (KD) mutants vary in their resistance to various tyrosine kinase inhibitors and therapeutic antibody trastuzumab (herceptin). The following ERBB2 KD mutants are resistant to the therapeutic antibody trastuzumab (herceptin):

ERBB2 L755P (Nagano et al. 2018);
ERBB2 L755S (Nagano et al. 2018);
ERBB2 I767M (Bose et al. 2013);
ERBB2 D769Y (Nagano et al. 2018);
ERBB2 V777L (Nagano et al. 2018);
ERBB2 P780_Y781insGSP (Bose et al. 2013, Nagano et al. 2018);
ERBB2 T798M (Rexer et al. 2013);
ERBB2 V842I (Nagano et al. 2018);
ERBB2 T862A (Nagano et al. 2018);
ERBB2 L869R (Hanker et al. 2017);

For ERBB2 R896C, both resistance (Bose et al. 2013) and sensitivity (Nagano et al. 2018) to trastuzumab have been reported.
