Who was studied 405,540 European ancestry individuals.
The effect
Each copy of the A allele shifted the measure 0.0687 lower (95% confidence interval 0.06-0.077); p = 2 × 10−56.
How common The A allele had a frequency of about 98% in the people studied.
Where it sits Chromosome 3, band 3p21.31 — between genes, 2.5 kb from SLC38A3.
What each result means
A/ATwo copies of the version the research linked to Height (baseline). 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 Height (baseline). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Height (baseline). This is the starting point the study compared everyone against.

Questions about rs557947378
What is rs557947378?
rs557947378 is a single position in the genome, in or near the near SLC38A3 gene. Published research associates it with height (baseline). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs557947378 linked to?
On MyGeneLog this position is linked to Height. The research behind each link, and its sources, are set out on that condition page.
Does having rs557947378 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 rs557947378 come from?
GWAS Catalog, Nature communications 2025, PMID:40374629. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
