Gastric cancer is still one of the world's leading causes of cancer mortality. Approximately 10% of gastric cancers appear to have a familial predisposition.

This mutation lead to the hereditary diffuse gastric cancer syndrome (HDGC). Other syndromes of familial prevalence of the gastric cancer, correlated with genetic mutations, are the hereditary nonpolyposis colorectal cancer, Li-Fraumeni syndrome, Peutz-Jeghers syndrome, Familial Adenomatous Polyposis, Cowden disease.
