PTCH1 · rs28704635
Where this position leads
Condition: Hip Circumference
Strength of the evidence
Its strongest genetic-study result is p = 10−14, 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 186,825 British ancestry men.
The effect Each copy of the A allele shifted the measure 0.0283 higher (95% confidence interval 0.021-0.035); p = 7 × 10−15.
Where it sits Chromosome 9, band 9q22.32 — between genes, 0 kb from PTCH1.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
rs28704635 is a single position in the genome, in or near the PTCH1 gene. Published research associates it with hip circumference adjusted for bmi. 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 Hip Circumference. 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.
