Where this position leads
Condition: Endometriosis
Strength of the evidence
Its strongest genetic-study result is p = 10−7, with 1 associations in the GWAS Catalog.
4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.
What the study found
Who was studied 2,481 African ancestry cases, 54,671 African ancestry controls, 1,752 Admixed American ancestry cases, 37,871 Admixed American ancestry controls, 2,044 East Asian ancestry cases, 87,723 East Asian ancestry controls, 99,407 European ancestry cases, 1,093,534 European ancestry controls, 185 Central/South Asian or Middle Eastern ancestry cases, 8,932 Central/South Asian or Middle Eastern ancestry controls.
The effect Each copy of the T allele shifted the measure 0.0104 lower (95% confidence interval 0.0067-0.0142); p = 5 × 10−8.
How common The T allele had a frequency of about 41% in the people studied.
Where it sits Chromosome 8, band 8q23.3 — in an intron of TRPS1.
rs800880 is a single position in the genome, in or near the TRPS1 gene. Published research associates it with endometriosis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Endometriosis. The research behind each link, and its sources, are set out on that condition page.
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.
