Who was studied 437 European ancestry individuals, 364 African American individuals, 453 Latino individuals, 674 Japanese American individuals, 311 Native Hawaiian ancestry individuals.
The effect
Each copy of the C allele shifted the measure 0.359 higher (95% confidence interval 0.31-0.41); p = 1 × 10−41.
Where it sits Chromosome 19, band 19q13.2 — between genes, 11.2 kb from CYP2A7.
What each result means
C/CTwo copies of the version the research linked to Nicotine metabolite ratio in current smokers. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Nicotine metabolite ratio in current smokers. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Nicotine metabolite ratio in current smokers. This is the starting point the study compared everyone against.
rs113029345 is a single position in the genome, in or near the CYP2A6 gene. Published research associates it with nicotine metabolite ratio in current smokers. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs113029345 linked to?
On MyGeneLog this position is linked to Nicotine and Cotinine Metabolism. The research behind each link, and its sources, are set out on that condition page.
Does rs113029345 affect how medicines work?
CYP2A6 carries pharmacogenomic findings for Smoking cessation medicines. That is educational information, not a prescription or a dosing guide. Any decision to start, stop or change a medicine belongs with the clinician or pharmacist managing your treatment.
Does having rs113029345 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs113029345 come from?
GWAS Catalog, Cancer Res 2016, PMID:27488534. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
