Where this position leads

What the study found

Who was studied 4,254 Japanese ancestry cases, 197,577 Japanese ancestry controls; replicated in 19,495 European ancestry cases, 258,943 European ancestry controls.

The effect Each copy of the T allele shifted the measure 0.0866 higher (95% confidence interval 0.064-0.109); p = 3 × 10⁻¹⁴.

How common The T allele had a frequency of about 63% in the people studied.

Where it sits Chromosome 6, band 6p21.2 — between genes, 8.1 kb from Y_RNA.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Heart failure with reduced ejection fraction — 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 Heart failure with reduced ejection fraction.

T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Heart failure with reduced ejection fraction compared to the general population.

Questions about rs4711456

What is rs4711456?

rs4711456 is a single position in the genome, in or near the near CDKN1A gene. Published research associates it with heart failure with reduced ejection fraction. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs4711456 linked to?

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

Does having rs4711456 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 rs4711456 come from?

GWAS Catalog, Nature communications 2025, PMID:41184235. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
