Endometriosis without adenomyosis

WNT4 · rs55938609

Where this position leads

What the study found

Who was studied 6,627 European ancestry cases, 283,316 European ancestry controls.

The effect Each copy of the C allele shifted the measure 0.0878 higher (95% confidence interval 0.063-0.112); p = 2 × 10⁻¹².

How common The C allele had a frequency of about 14% in the people studied.

Where it sits Chromosome 1, band 1p36.12 — in an intron of WNT4.

What each result means

C/C Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Endometriosis without adenomyosis compared to the general population.

C/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Endometriosis without adenomyosis.

G/G Published research associates this genotype with typical/baseline likelihood of Endometriosis without adenomyosis — no copies of the reported risk allele.

Questions about rs55938609

What is rs55938609?

rs55938609 is a single position in the genome, in or near the WNT4 gene. Published research associates it with endometriosis without adenomyosis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs55938609 linked to?

On MyGeneLog this position is linked to Endometriosis. The research behind each link, and its sources, are set out on that condition page.

Does having rs55938609 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 rs55938609 come from?

GWAS Catalog, Nature genetics 2026, PMID:42056605. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
