Scientists at Johns Hopkins large, multi-institutional research as part of one gene variant found associated with lung cancer risk. A study on the State of nature Genetics April 3 to be appropriate in the circumstances.The research team will 1,154 smokers with lung cancer and lung cancer 1,137 smokers without DNA collected.Each DNA sample was analyzed at more than 300 000, looking for a single nucleotide polymorphisms variationsknown or SNPs for shortbetween cancer and then analyze Them without the top 10 new SNPs 5,075 with DNA samples and without the complication of smokers.
Two 10 SNPs were consistently associated with lung cancer risk and both are located on the inside, that contains the nicotinic acetylcholine receptor Alpha subunits 3 and 5, which already suspected lung cancer progression of the genes involved in chromosome 15.
The research team will then wondered if these genetic associations related to nicotine dependence on, and found that two of the same SNPs also weakly related to the tobacco problem.
Genome-wide analysis of power cannot search for the number of characters and number of specimens that may reveal complex diseases such as lung cancer due to poor genetic associations. Kimberly Doheny, Ph.d., Center for previous diseases Research, McKusick Nathansin Institute of Genetic Medicine, Assistant to the Director of the Johns Hopkins says.
