Genetics could put some smokers at an even higher risk of developing chronic obstructive pulmonary disease (COPD) according to a team of scientists at this year’s Royal Society Summer Science Exhibition which opens today (3 July). The researchers are studying the genetic variations which predict lung health.

According to a team from the University of Leicester, lead by GENIE, the Centre for Excellence in Teaching and Learning in Genetics, a person's chances of developing COPD as they grow older is affected by whether they smoke cigarettes, but genetic variation also plays a role. Understanding the genetic variation that predicts lung disease gives scientists clues about the causes of lung disease and about how to treat it.

Lead exhibitor Professor Martin Tobin, along with an international consortium of 175 scientists, has been able to identify twenty-six common genetic variants definitely linked with lung function. The researchers say the new pathways discovered could lead to better drugs and treatments for COPD - a progressive disease, affecting around 1 in 10 adults above the age of 40, which makes it hard for people to breathe and is the fourth most common cause of death worldwide.

Commenting on the research his team will be presenting Professor Martin Tobin said:

“The risks to lung health posed by smoking are now well accepted but what if you knew your personal genetic make-up could put you at an even higher risk? Would this make you quit or stop you from starting in the first place? At this point it is too early to say whether this research could be used to create a screening test to predict the development of COPD but it does offer us a starting point for understanding the factors which underlie inherited variability in lung function.   Avoiding taking up smoking and stopping smoking remain the best ways to prevent COPD.”

To identify the genetic variations that affect lung health the scientists behind the exhibit compared millions of differences in the DNA of almost 50,000 people and checked how healthy their lungs were. The DNA in our cells is made up of three billion pairs of just four types of chemical bases: known as A, C, G and T. Genetic variation means that, where one person might have an A at a certain place in the sequence, another person might have a G.

The researchers hope to use the knowledge gained from this study to learn more about the function of genes which contribute to the risk of developing lung diseases such as COPD and to try and develop strategies to use genetic information to improve the clinical care provided to individual patients

At the exhibition, visitors will be able to see how lung health is measured and learn about genetic variation between people. They will also be able to try detecting the genetic variations which predict lung health.

The exhibition opens to the public on Tuesday 3 July 2012.
