Genetics in Gastroenterology

Genetics and genomics are beginning to strongly influence the care of patients with gastrointestinal conditions. From common disorders such as colorectal cancer, pancreatitis, and multiple polyps; too rare conditions like hereditary haemorrhagic telangiectasia, knowledge of genomic developments is increasingly highly useful to doctors and their patients. Rapid advances in genetics have led to an increased understanding of the genetic determinants of human disease, including many gastrointestinal disorders. Coupled with a proliferation of genetic testing services, this has resulted in a clinical landscape where commercially available genetic tests for gastrointestinal disorders are now widely available.
