White blood cell count

TSPO · rs138917

What the study found

Who was studied 507,850 East Asian ancestry individuals, 420,829 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0145 lower (95% confidence interval 0.01-0.019); p = 4 × 10−11.

Where it sits Chromosome 22, band 22q13.2 — in an intron of TSPO.

What each result means

G/G Published research associates this genotype with typical/baseline likelihood of White blood cell count — no copies of the reported risk allele.
G/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with White blood cell count.
T/T 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.

Questions about rs138917

What is rs138917?

rs138917 is a single position in the genome, in or near the TSPO 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 rs138917 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 rs138917 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.
