Who was studied 123 European ancestry cases, 2,964 European ancestry controls; replicated in 84 European ancestry cases, 1,134 European ancestry controls.
The effect
Each copy of the A allele carried 4.75 times the odds of Polycystic ovary syndrome (reproductive subtype) (95% confidence interval 2.82-7.98); p = 2 × 10−10.
How common The A allele had a frequency of about 2% in the people studied.
Where it sits Chromosome 1, band 1p36.21 — in an intron of KAZN-AS1.
What each result means
A/ATwo copies of the version the research linked to Polycystic ovary syndrome (reproductive subtype). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Polycystic ovary syndrome (reproductive subtype). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Polycystic ovary syndrome (reproductive subtype). This is the starting point the study compared everyone against.

Questions about rs78025940
What is rs78025940?
rs78025940 is a single position in the genome, in or near the KAZN gene. Published research associates it with polycystic ovary syndrome (reproductive subtype). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs78025940 linked to?
On MyGeneLog this position is linked to Polycystic Ovary Syndrome. The research behind each link, and its sources, are set out on that condition page.
Does having rs78025940 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 rs78025940 come from?
GWAS Catalog, PLoS Med 2020, PMID:32574161. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
