Helicobacter pylori Genome Project (HpGP)

Investigators in the Metabolic Epidemiology Branch, Infections and Immunoepidemiology Branch, Biostatistics Branch, and the NCI Center for Cancer Research, in collaboration with an international, multi-disciplinary team, have created an international biobank of clinically annotated genetic and epigenetic variations of Helicobacter pylori (H. pylori), the only confirmed bacterial carcinogen. H. pylori causes more than 850,000 cases of gastric cancer each year.

The goal of the study was to sequence 1000 strains of H. pylori from populations around the globe that experience both low and high risk of gastric cancer and identify long-term outcomes of infection and associations between persistent infection and the gastric carcinogenesis cascade.
