The study recommended CDH1 genetic testing for individuals with a family history of LBC, even in the absence of DGC, and pointed out that other genes, such as BRCA2, CHEK2, ATM, and PALB2, are also associated with LBC (Blair et al. 2020). The gene discussed is BRCA2; the disease is CDH1-related diffuse gastric and lobular breast cancer syndrome.
