Who was studied 172,952 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.0229 lower (95% confidence interval 0.015-0.031); p = 4 × 10−9.
How common The T allele had a frequency of about 70% in the people studied.
Where it sits Chromosome 20, band 20q13.12 — in an intron of TOX2.
What each result means
C/CPublished research associates this genotype with typical/baseline likelihood of Red blood cell count — no copies of the reported risk allele.
C/TPublished research associates this genotype (one copy of the reported risk allele) with an intermediate association with Red blood cell count.
T/TPublished research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Red blood cell count compared to the general population.
rs766622 is a single position in the genome, in or near the TOX2 gene. Published research associates it with red blood cell count. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs766622 linked to?
On MyGeneLog this position is linked to Blood Cell Counts. The research behind each link, and its sources, are set out on that condition page.
Does having rs766622 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 rs766622 come from?
GWAS Catalog, Cell 2016, PMID:27863252. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
