One such case was reported in Korea in 2014 where a 44-year-old male, who on genetic testing presented a family history of gastric cancer with no symptoms, visited the clinic for genetic testing and then later on was found to have a CDH1 mutation, with this being one of the first cases reported in the region with such history and mutation during the time and so was kept on regular endoscopic surveillance [30]. This evidence concerns the gene CDH1 and gastric cancer.
