Genomic study on ulcers in European and Asian populations could lead to new population-specific treatments

Researchers studied stomach and duodenal ulcers in a large research project comparing Japanese and European populations. They found 25 new genetic markers linked to ulcers which showed that, though these sores on the walls of the stomach and of the duodenum (the beginning part of the small intestine) share some genetic factors, stomach ulcers have more possible causes.
