Who was studied 426,824 British ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0146 lower (95% confidence interval 0.011-0.019); p = 3 × 10−12.
How common The A allele had a frequency of about 72% in the people studied.
Where it sits Chromosome 18, band 18q21.1 — in an intron of SMAD7.
What each result means
A/ATwo copies of the version the research linked to Heel bone mineral density. 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 Heel bone mineral density. That is a smaller link than two copies.
C/CNo copy of the version the research linked to Heel bone mineral density. This is the starting point the study compared everyone against.

Questions about rs12956326
What is rs12956326?
rs12956326 is a single position in the genome, in or near the SMAD7 gene. Published research associates it with heel bone mineral density. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs12956326 linked to?
On MyGeneLog this position is linked to Heel Bone Mineral Density. The research behind each link, and its sources, are set out on that condition page.
Does having rs12956326 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 rs12956326 come from?
GWAS Catalog, Nature genetics 2019, PMID:30598549. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
