Where this position leads

Condition: Alcohol Consumption

rs140089781 Condition: Alcohol Consumption Alcohol Consumption Condition rs140089781 rs140089781 CTNNA2

What the study found

Who was studied 59,088 European ancestry females, 53,029 European ancestry males.

The effect Each copy of the A allele shifted the measure 0.024 lower (95% confidence interval 0.016-0.032); p = 4 × 10−8.

How common The A allele had a frequency of about 0% in the people studied.

Where it sits Chromosome 2, band 2p12 — in an intron of CTNNA2.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Alcohol consumption compared to the general population.
A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Alcohol consumption.
G/G Published research associates this genotype with typical/baseline likelihood of Alcohol consumption — no copies of the reported risk allele.

Questions about rs140089781

What is rs140089781?

rs140089781 is a single position in the genome, in or near the CTNNA2 gene. Published research associates it with alcohol consumption. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs140089781 linked to?

On MyGeneLog this position is linked to Alcohol Consumption. The research behind each link, and its sources, are set out on that condition page.

Does having rs140089781 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 rs140089781 come from?

GWAS Catalog, Mol Psychiatry 2017, PMID:28937693. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
