Waist-hip ratio

CNTN2 · rs3903399

Where this position leads

Condition: Waist-to-Hip Ratio (Body Fat Distribution)

What the study found

Who was studied 697,734 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0149 lower (95% confidence interval 0.011-0.019); p = 7 × 10⁻¹².

How common The T allele had a frequency of about 78% in the people studied.

Where it sits Chromosome 1, band 1q32.1 — in an intron of CNTN2.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Waist-hip ratio — no copies of the reported risk allele.

C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Waist-hip ratio.

T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Waist-hip ratio compared to the general population.

Questions about rs3903399

What is rs3903399?

rs3903399 is a single position in the genome, in or near the CNTN2 gene. Published research associates it with waist-hip ratio. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs3903399 linked to?

On MyGeneLog this position is linked to Waist-to-Hip Ratio (Body Fat Distribution). The research behind each link, and its sources, are set out on that condition page.

Does having rs3903399 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 rs3903399 come from?

GWAS Catalog, Hum Mol Genet 2018, PMID:30239722. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
