Its strongest genetic-study result is p = 10−24, with 2 associations in the GWAS Catalog.
How this is scored
4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.
What the study found
Who was studied 344,104 European ancestry individuals, 133,471 East Asian ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0242 higher (95% confidence interval 0.02-0.029); p = 7 × 10−25.
Where it sits Chromosome 3, band 3q22.3 — in an intron of STAG1.
What each result means
A/ATwo copies of the version the research linked to Gamma glutamyl transpeptidase. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/COne copy of the version the research linked to Gamma glutamyl transpeptidase. That is a smaller link than two copies.
C/CNo copy of the version the research linked to Gamma glutamyl transpeptidase. This is the starting point the study compared everyone against.
rs9868120 is a single position in the genome, in or near the STAG1 gene. Published research associates it with gamma glutamyl transpeptidase. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs9868120 linked to?
On MyGeneLog this position is linked to Colon Polyp. The research behind each link, and its sources, are set out on that condition page.
Does having rs9868120 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 rs9868120 come from?
GWAS Catalog, Nature genetics 2021, PMID:34594039. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
