In fact, they also found genetic variants of COPD in people who do not smoke and never smoked in their life.

COPD is a global health concern as a lot of people is affected by it across the globe.
This can be low or high, depending on the person, and stands as the basis of the lung function phenotypes the research team was looking for. Those suffering from the basket of lung illnesses bundled together under the Chronic Obstructive Pulmonary Disease banner were found to have a genetic predisposition to lung disease or basically more rubbish lungs than the healthier section of smoking society, leading medical professionals to hope new methods of battling such diseases might now come to light.
What’s more, the scientific community now has proof that there’s a shared genetic architecture between airflow obstruction in heavy smokers and airflow obstruction in non-smokers. If the amount of air exhaled is measured during the first second, this is FEV1.
British researchers looked at data collected from a little over 50,000 people in the UK’s Biobank project and noticed that they had favorable mutations in their DNA. In this way, they were able to compare lung health and smoking behavior with both common and rare genetic variations across the whole human genome.
Researchers analyzed data from 24 case-control studies from the worldwide Lung Cancer Consortium-conducted in North America, Europe, Asia and Oceania-that included 4,346 people with SCLC and 37,942 without the disease. Apparently, chromosome 17 was linked to lung health in both smokers and nonsmokers.
Hall said: “The drugs we use to prevent or treat diseases target the proteins in our bodies, and our genes influence the production of proteins”.
Not only does smoking hurt the lungs warned researchers, but also it increases the risk of cancer and heart disease, which were not taken into consideration in the study. Looking at these statistics and trying to understand the deeper link between COPD and other factors that impair proper lung function, such as smoking behavior, Professor Ian Hall with the University of Nottingham Queen’s Medical Center in collaboration with a wider research team generated an extensive research database from the United Kingdom Biobank. “A full understanding of the biological mechanisms underlying these genetic associations will improve our understanding of the pathophysiology of COPD and smoking behaviour, and potentially give rise to novel therapeutic strategies for the management of airway disease and prevention of nicotine addiction”.

The authors are optimistic that the study will ultimately lead to new and improved approaches for helping people to stop smoking and for prevention and treatment of COPD.
