Its strongest genetic-study result is p = 10−21, with 1 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 14,498 European ancestry cases, 24,091 European ancestry controls; replicated in 14,802 European ancestry cases, 26,703 European ancestry controls.
The effect
Each copy of the A allele carried 1.13 times the odds of Multiple sclerosis (95% confidence interval -); p = 9 × 10−22.
How common The A allele had a frequency of about 67% in the people studied.

What each result means
A/ATwo copies of the version the research linked to Multiple sclerosis. 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 Multiple sclerosis. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Multiple sclerosis. This is the starting point the study compared everyone against.

Questions about rs201202118
What is rs201202118?
rs201202118 is a single position in the genome, in or near the TSFM gene. Published research associates it with multiple sclerosis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs201202118 linked to?
On MyGeneLog this position is linked to Multiple Sclerosis. The research behind each link, and its sources, are set out on that condition page.
Does having rs201202118 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 rs201202118 come from?
GWAS Catalog, Nat Genet 2013, PMID:24076602. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
