Major new discovery of genes that predispose for severe disease

New chapter opens in history of medicine, as researchers announced the discovery of new genes associated with serious diseases. The new discovery is published in the journal 'Nature' and is expected to pave the way for further research and treatment of genetic test.

Researchers examining the DNA of blood 17,000 people, found that genes contribute to the onset of depression, diabetes, disease of Crohn, rheumatoid arthritis, hypertension and coronary disease.

The research team emphasizes that the discovery of genes that contribute to the emergence of serious diseases research will lead scientists to better understand the mechanism of disease, identify people at risk to develop, and will shortly be able to develop more effective and personalized medicines.

As stated, many of the most common diseases are very complex and depend on genetic and environmental factors in combination with lifestyle.

Scientists said that although in the past had little lights turn to the long dark tunnel of the genome, now turn lights in many parts of the tunnel, in this case half a million lights.

In case 1 diabetes gene discovered several areas that increase the risk of disease. The researchers of the project took part in the recent announcements of the discovery of obesity gene, three new genes linked to diabetes 2 and region of chromosome 9 associated with heart disease.

One of the most important discoveries is that a gene that was previously unknown is common and the emergence of diabetes and 1 in disease Chron, an inflammatory bowel disease, indicating that the two diseases share common biological pathways.

Many of the genes discovered by a team of 200 scientists were in parts of the genome not previously been regarded as potentially linked to illnesses.

In the future could allow people to look for combinations of genes to predict the risk they face in their entire lives to outbreaks of disease, which will lead them to change their lifestyles or be considered timely.

Professor of Statistics, Peter Donnelly, who took part in the investigation, said that the investigation is a new beginning and that researchers have learned more the past 12 months than they had learned the previous 15 years.
