From BBC News:
The landmark Wellcome Trust study analysed DNA from the blood of 17,000 people to find genetic differences. They found new genetic variants for depression, Crohn’s disease, coronary heart disease, hypertension, rheumatoid arthritis and type 1 and 2 diabetes. The remarkable findings, published in Nature, have been hailed as a new chapter in medical science. It is hoped they will pave the way for research into new treatments and genetic tests.
One of the most exciting finds was a previously unknown gene common to type 1 diabetes and Crohn’s disease, a type of inflammatory bowel disorder, suggesting that they share similar biological pathways. The team also unexpectedly found a process known as autophagy – a process of clearing bacteria from within cells – is important in the development of Crohn’s disease.
