Its strongest genetic-study result is p = 10−13, with 4 associations in the GWAS Catalog.
How this is scored
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 up to 56,910 European ancestry men, up to 86,570 European ancestry women; replicated in up to 36,570 European ancestry men, 30,172 European ancestry women, 915 Filipino ancestry men, 735 Filipino ancestry women, 2,351 African American/Afro-Caribbean ancestry men, 6,258 African American/Afro-Caribbean ancestry women, 2,285 South Asian ancestry men, 506 South Asian ancestry women, 195 Seychellois ancestry men, 266 Seychellois ancestry women.
The effect
Each copy of the C allele shifted the measure 0.0287 lower (95% confidence interval 0.021-0.036); p = 2 × 10−13.
How common The C allele had a frequency of about 75% in the people studied.
Where it sits Chromosome 4, band 4q21.21 — between genes, 21.2 kb from PRKG2.

What each result means
C/CTwo copies of the version the research linked to Waist circumference adjusted for body mass index. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/GOne copy of the version the research linked to Waist circumference adjusted for body mass index. That is a smaller link than two copies.
G/GNo copy of the version the research linked to Waist circumference adjusted for body mass index. This is the starting point the study compared everyone against.
rs2197271 is a single position in the genome, in or near the PRKG2 gene. Published research associates it with waist circumference adjusted for body mass index. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs2197271 linked to?
On MyGeneLog this position is linked to Waist Circumference. The research behind each link, and its sources, are set out on that condition page.
Does having rs2197271 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 rs2197271 come from?
GWAS Catalog, Nature 2015, PMID:25673412. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
