a gPALB2 patient. Sequence alignment from the PALB2 locus comparing pre- (top) and post-treatment (bottom) sequence in a responding patient (confirmed PR) with gPALB2-related breast cancer. Germline alteration is shown in red, and upstream acquired somatic deletion is shown in green (upper panel). The secondary mutation is predicted to restore a near full-length PALB2 protein (lower panel). b gBRCA2 patient. Sequence alignment from the BRCA2 locus comparing pre- (top) and post-treatment (bottom) sequence in a patient with gBRCA2-related pancreatic cancer, who experienced clinical benefit (best response SD; 13% shrinkage in target lesions, with improvement in tumor markers and disease-related symptoms), followed by progression. Germline alteration is shown in red, and downstream acquired somatic deletion is shown in green (upper panel). The secondary mutation is predicted to restore a near full-length BRCA2 protein (lower panel).
