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 507,850 East Asian ancestry individuals, 420,829 European ancestry individuals.

The effect Each copy of the A allele shifted the measure 0.0094 lower (95% confidence interval 0.0065-0.0123); p = 3 × 10⁻¹⁰.

Where it sits Chromosome 6, band 6q24.3 — in an intron of STXBP5.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of White blood cell count compared to the general population.

A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with White blood cell count.

G/G Published research associates this genotype with typical/baseline likelihood of White blood cell count — no copies of the reported risk allele.

Questions about rs9390463

What is rs9390463?

rs9390463 is a single position in the genome, in or near the STXBP5 gene. Published research associates it with white blood cell count. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs9390463 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 rs9390463 come from?

GWAS Catalog, Nature communications 2025, PMID:40436827. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
