Who was studied 778 European ancestry cases, 4,414 European ancestry controls, 242 Ashkenazi Jewish cases, 354 Ashkenazi Jewish controls, 265 French Canadian founder cases, 196 French Canadian founder controls; replicated in 211 Latin American cases, 285 Latin American controls.
The effect
Each copy of the G allele carried 1.29 times the odds of Tourette syndrome; p = 3 × 10−8.
How common The G allele had a frequency of about 28% in the people studied.
Where it sits Chromosome 9, band 9q32 — in an intron of COL27A1.
What each result means
A/ANo copy of the version the research linked to Tourette syndrome. This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to Tourette syndrome. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Tourette syndrome. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs7868992
What is rs7868992?
rs7868992 is a single position in the genome, in or near the COL27A1 gene. Published research associates it with tourette syndrome. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs7868992 linked to?
On MyGeneLog this position is linked to Tourette Syndrome. The research behind each link, and its sources, are set out on that condition page.
Does having rs7868992 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 rs7868992 come from?
GWAS Catalog, Mol Psychiatry 2012, PMID:22889924. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
