Who was studied 3,037,499 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0132 lower (95% confidence interval 0.011-0.015); p = 2 × 10−35.
How common The A allele had a frequency of about 58% in the people studied.
Where it sits Chromosome 18, band 18q11.2 — between genes, 20 kb from ZNF521.
What each result means
A/ATwo copies of the version the research linked to Educational attainment. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/TOne copy of the version the research linked to Educational attainment. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Educational attainment. This is the starting point the study compared everyone against.

Questions about rs9956721
What is rs9956721?
rs9956721 is a single position in the genome, in or near the near ZNF521 gene. Published research associates it with educational attainment. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs9956721 linked to?
On MyGeneLog this position is linked to Educational Attainment. The research behind each link, and its sources, are set out on that condition page.
Does having rs9956721 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 rs9956721 come from?
GWAS Catalog, Nature genetics 2022, PMID:35361970. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
