Who was studied 2,663 European ancestry cases, 13,498 European ancestry controls; replicated in 10,282 European ancestry cases, 21,093 European ancestry controls.
The effect
Each copy of the T allele carried 1.15 times the odds of Schizophrenia; p = 2 × 10−9.
How common The T allele had a frequency of about 83% in the people studied.
Where it sits Chromosome 11, band 11q24.2 — between genes, 3.5 kb from NRGN.
What each result means
C/CNo copy of the version the research linked to Schizophrenia. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Schizophrenia. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Schizophrenia. That is the strongest link of the three results. A link in a study is not a diagnosis.
Papers in Europe PMC whose title or abstract names both this rsID and that subject. A shared paper means somebody wrote about the two together — it is not a claim that this position explains the subject.
Questions about rs12807809
What is rs12807809?
rs12807809 is a single position in the genome, in or near the NRGN gene. Published research associates it with schizophrenia. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs12807809 linked to?
On MyGeneLog this position is linked to Schizophrenia. The research behind each link, and its sources, are set out on that condition page.
What do people read about alongside rs12807809?
Subjects that appear in the title or abstract of the same papers as this rsID include learning and focus (2 papers), brain and memory (2 papers), depression and stress (1 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.
Does having rs12807809 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 rs12807809 come from?
GWAS Catalog, Nature 2009, PMID:19571808. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
