Tobacco Exposure And Genetics Linked To Lung Cancer Risk
An article in Medical News Today reports about a study done on the genotype of the gene rs1051730-rs16969968. Studies show that this genotype is linked with objective measures of tobacco. This link indicates that lung cancer is mostly caused by the level of tobacco exposure.
The study was done by Marcus R. Munafò, Ph.D., of the School of Experimental Psychology at the University of Bristol and his team. In their research, they found that even after adjusting the self-reported cigarette consumption, the rs1051730-rs16969968 genotype is strongly linked to tobacco exposure through cotinine levels.
This research is significant because past studies were generally based on the participant’s self-reported smoking habits, but this could have led to overlooking certain links.
