Researchers from the University of Leicester and University of Nottingham are leading the largest ever study of the genetics relating to lung disease.

The project will investigate what determines an individual’s lung health and why smoking harms the lungs of some people more than others and will use health information held by UK Biobank, a major national resource holding health information from half a million volunteers.

The study, funded by the Medical Research Council (MRC) and also involving scientists at St George’s, University of London, is aiming to shed light on why some people are genetically more prone to suffer from lung disease, particularly chronic obstructive pulmonary disease (COPD).

COPD includes conditions such as chronic bronchitis and emphysema and is the sixth most common cause of death in the UK (around 30,000 deaths per year). It affects approximately 900,000 people in the UK and costs the NHS £150m every year. At present, avoiding taking up smoking or, for those who already smoke, stopping smoking remain the most effective ways to prevent COPD.

The World Health Organisation (WHO) estimates that COPD is the 4th leading cause of death worldwide but it is predicted to move into 3rd place in the near future. The new project is being launched on Wednesday November 14, which is World COPD Day.

The research aims to discover the genes which affect lung function and also those which may affect the chances of developing lung disease for both smokers and non-smokers. It will also investigate whether genes play a part in the ability, or failure, to maintain good lung health for smokers and non-smokers. The researchers will also be able to investigate genetic factors that may affect the likelihood of an individual becoming addicted to smoking.

The study, which is called UK BiLEVE (UK Biobank Lung Exome Variant Evaluation), will be one of the first projects to make use of UK Biobank, the world’s largest resource of its kind.

All UK Biobank participants have already had their lung function measured and given information about their smoking habits, past and present. In this study, researchers will use anonymous data from 50,000 of these participants to determine genetic variants associated with susceptibility to COPD. They will look at both rare and common single nucleotide polymorphisms (tiny variations in genes) in the participants’ DNA and the lung function of those who are heavy smokers and those who have never smoked.

Leading the research in Leicester is Professor Martin Tobin. He said: “We currently know very little about why lung health varies so much between people. Not all smokers are equally susceptible to developing lung disease. Inheritance plays an important role so we’re delighted to be able to use UK Biobank to discover which genetic variants affect lung health. This is a unique study which couldn’t be done anywhere else in the world.”

Professor David Lomas, Chair of the MRC Population and Systems Medicine Board, said: “We know that smoking is unhealthy for anyone but we know little about why the lungs of most smokers are seriously affected, while those of some seem to stay relatively healthy. If we knew more about the genetics that cause this variation we would be better able to direct treatments to those who are most at risk and have an increased chance of developing drugs to target this type of lung disease.”
