What the study found

Who was studied up to 433,216 European ancestry individuals.

The effect Each copy of the C allele shifted the measure 0.0265 lower (95% confidence interval 0.02-0.033); p = 2 × 10−17.

How common The C allele had a frequency of about 84% in the people studied.

Where it sits Chromosome 6, band 6q21 — in an intron of REV3L.

What each result means

C/C Published 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.
C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Smoking initiation (ever regular vs never regular).
T/T Published research associates this genotype with typical/baseline likelihood of Smoking initiation (ever regular vs never regular) — no copies of the reported risk allele.

Questions about rs240963

What is rs240963?

rs240963 is a single position in the genome, in or near the REV3L 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 rs240963 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 rs240963 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 rs240963 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.
