Investigation on the Role of PALB2 Gene in CDH1-Negative Patients With Hereditary Diffuse Gastric Cancer.

Introduction: Not all patients with hereditary diffuse gastric cancer (HDGC) are found to carry germline pathogenic variants in the associated gene CDH1, which translates into a challenging clinical management and poor cancer prevention. Thus, several studies have searched for other candidate genes, among which stands PALB2. Our work explores the implication of this known cancer gene in HDGC.
