Georgia State researchers unlock key to deadly disease

International researchers led by Georgia State University scientists have identified a gene that when working correctly prevents a fatal disease affecting about 140,000 Americans.

Understanding the gene, CLYD, is an important first step in battling pulmonary fibrosis, officials said Tuesday. Next researchers must find ways to turn on the gene or make it last longer if it's not working right.

The gene's failure to function can lead to scarring of the lungs, eventually killing the patient. People with the disease typically live three to five years after diagnosis.
