ACAN · rs3817428
Where this position leads
Conditions: Waist-to-Hip Ratio (Body Fat Distribution), Osteoarthritis
Strength of the evidence
Its strongest genetic-study result is p = 10−38, with 30 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 55,006 British ancestry males, 61,132 British ancestry females; replicated in 112,425 British ancestry males, 133,936 British ancestry females.
The effect Each copy of the G allele shifted the measure 0.0335 lower; p = 1 × 10−38.
How common The G allele had a frequency of about 26% in the people studied.
Where it sits Chromosome 15, band 15q26.1 — a missense change in ACAN.

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.
rs3817428 is a single position in the genome, in or near the ACAN gene. Published research associates it with body fat distribution (trunk fat ratio). 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 Waist-to-Hip Ratio (Body Fat Distribution), Osteoarthritis. 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.
