Where this position leads

What the study found

Who was studied 365,998 European ancestry individuals, 63,490 African ancestry individuals, 22,802 Hispanic individuals, 4,792 Asian ancestry individuals, 2,695 Native American ancestry individuals; replicated in 299,024 European ancestry individuals, 17,277 individuals.

The effect Each copy of the T allele shifted the measure 0.178 mmHg higher (95% confidence interval 0.12-0.23); p = 1 × 10⁻¹⁰.

How common The T allele had a frequency of about 48% in the people studied.

Where it sits Chromosome 1, band 1q25.3 — in an intron of C1orf21.

What each result means

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

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

Questions about rs4651224

What is rs4651224?

rs4651224 is a single position in the genome, in or near the C1orf21 gene. Published research associates it with systolic 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 rs4651224 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 rs4651224 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 rs4651224 come from?

GWAS Catalog, Nat Genet 2018, PMID:30578418. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
