摘要: Germline changes in the CDH1 tumor suppressor gene predispose to diffuse gastric cancer and lobular breast cancer. In carriers of deleterious germline variants, prophylactic gastrectomy is recommended. case missense it mandatory assess functional impact on E-cadherin, protein encoded by CDH1, predict their clinical significance. Herein, we have identified a recurrent variant, c.1679C>G, segregating with three unrelated Spanish families. Through genetic, transcriptional, silico vitro studies, demonstrate effect c.1679C>G variant its association hereditary cancer, providing relevant data relatives allowing an accurate genetic counseling.
