Who was studied up to 433,216 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0131 higher (95% confidence interval 0.0085-0.0177); p = 4 × 10−8.
How common The A allele had a frequency of about 64% in the people studied.
Where it sits Chromosome 5, band 5q14.1 — in an intron of RASGRF2.
What each result means
A/APublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Smoking initiation (ever regular vs never regular) compared to the general population.
A/GPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Smoking initiation (ever regular vs never regular).
G/GPublished research associates this genotype with typical/baseline likelihood of Smoking initiation (ever regular vs never regular) — no copies of the reported risk allele.
rs13357015 is a single position in the genome, in or near the RASGRF2 gene. Published research associates it with smoking initiation (ever regular vs never regular). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs13357015 linked to?
On MyGeneLog this position is linked to Smoking Behaviour and Nicotine Dependence. The research behind each link, and its sources, are set out on that condition page.
Does having rs13357015 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 rs13357015 come from?
GWAS Catalog, Biol Psychiatry 2018, PMID:30679032. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
