Where this position leads

What the study found

Who was studied 130,777 Japanese ancestry individuals; replicated in 53,008 East Asian individuals, 105,253 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.583 lower (95% confidence interval 0.44-0.73); p = 3 × 10⁻¹⁵.

How common The T allele had a frequency of about 91% in the people studied.

Where it sits Chromosome 3, band 3p21.1 — in an intron of CACNA1D.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Diastolic blood pressure — 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 Diastolic blood pressure.

T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Diastolic blood pressure compared to the general population.

Questions about rs3774447

What is rs3774447?

rs3774447 is a single position in the genome, in or near the CACNA1D gene. Published research associates it with diastolic blood pressure. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs3774447 linked to?

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

Does having rs3774447 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 rs3774447 come from?

GWAS Catalog, Nat Commun 2018, PMID:30487518. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
