Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
What the study found
Who was studied 482,873 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.026 higher (95% confidence interval 0.022-0.03); p = 8 × 10−24.
How common The A allele had a frequency of about 23% in the people studied.
Where it sits Chromosome 15, band 15q22.31 — in an intron of SMAD6.
What each result means
A/ATwo copies of the version the research linked to Thyroid stimulating hormone levels. 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 Thyroid stimulating hormone levels. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Thyroid stimulating hormone levels. This is the starting point the study compared everyone against.

Questions about rs12902353
What is rs12902353?
rs12902353 is a single position in the genome, in or near the SMAD6 gene. Published research associates it with thyroid stimulating hormone levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs12902353 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 rs12902353 come from?
GWAS Catalog, Nature genetics 2025, PMID:41238958. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
