What the study found

Who was studied 810,865 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0957 mmHg higher (95% confidence interval 0.064-0.128); p = 1 × 10−9.

How common The A allele had a frequency of about 53% in the people studied.

Where it sits Chromosome 3, band 3q25.32 — a missense change in GFM1.

What ClinVar records

Classification Benign for Hepatoencephalopathy due to combined oxidative phosphorylation defect type 1; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 11 submitters), last evaluated 2026-02-04. ClinVar record 343925 NM_024996.7(GFM1):c.643G>A (p.Val215Ile)

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

A/A Two copies of the version the research linked to Diastolic blood pressure. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Diastolic blood pressure. That is a smaller link than two copies.
G/G No copy of the version the research linked to Diastolic blood pressure. This is the starting point the study compared everyone against.

Questions about rs2303909

What is rs2303909?

rs2303909 is a single position in the genome, in or near the GFM1 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 rs2303909 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 rs2303909 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 rs2303909 come from?

GWAS Catalog, Nature genetics 2020, PMID:33230300. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
