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 167,966 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.021 lower (95% confidence interval 0.013-0.029); p = 4 × 10⁻⁸.

How common The T allele had a frequency of about 18% in the people studied.

Where it sits Chromosome 1, band 1q42.2 — in an intron of SLC35F3.

What each result means

C/C Published research associates this genotype with typical/baseline likelihood of Stool frequency — no copies of the reported risk allele.

C/T Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Stool frequency.

T/T Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Stool frequency compared to the general population.

Questions about rs12407945

What is rs12407945?

rs12407945 is a single position in the genome, in or near the SLC35F3 gene. Published research associates it with stool frequency. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs12407945 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 rs12407945 come from?

GWAS Catalog, Gut 2026, PMID:41558814. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
