Stands on its own. Nothing else here links to this position yet — but the page above is the point: what the research found, what each genotype means, and where it came from, in language you can read. Links to conditions, drugs and the senses appear automatically if we write them.

What the study found

Who was studied 327,177 European ancestry individuals, 4,847 African ancestry individuals, 6,895 South Asian ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0274 lower (95% confidence interval 0.021-0.034); p = 4 × 10⁻¹⁵.

Where it sits Chromosome 2, band 2p23.3 — a missense change in MFSD2B.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Glycated hemoglobin levels compared to the general population.

A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Glycated hemoglobin levels.

G/G Published research associates this genotype with typical/baseline likelihood of Glycated hemoglobin levels — no copies of the reported risk allele.

Questions about rs3731620

What is rs3731620?

rs3731620 is a single position in the genome, in or near the MFSD2B gene. Published research associates it with glycated hemoglobin levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs3731620 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 rs3731620 come from?

GWAS Catalog, Nature genetics 2021, PMID:33462484. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
