Rare genetic variant linked to lung cancer in non-smokers, study finds
STAT reports that scientists identified a rare genetic mutation linked to a 25-fold increased lung cancer risk in never-smokers.
The short version
- Researchers analyzing 23andMe genetic data identified a rare variant linked to 25-fold higher odds of lung cancer in people who never smoked.[STAT]
- The gene variant is significantly more prevalent among residents of Southern Appalachia than in other U.S. regions.[STAT]
- Experts state the mutation accounts for only a minor fraction of non-smoker lung cancer cases but could influence future screening and treatment approaches.[STAT]
Key facts
- A rare genetic variant increases the odds of lung cancer in never-smokers by 25-fold, according to a study published in Science.[STAT]
- The identified genetic variant is notably more common in Southern Appalachia compared to other regions in the United States.[STAT]
- Investigators uncovered the mutation by analyzing large-scale genetic information provided by 23andMe.[STAT]
What remains uncertain
- The exact proportion of non-smoker lung cancer cases explained by this genetic variant remains uncertain, though experts estimate it is small.[STAT]
