Standard

Waist circumference adjusted for body mass index

PRKG2 · rs2197271

Strength of the evidence

1 / 4

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/C Two 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/G One copy of the version the research linked to Waist circumference adjusted for body mass index. That is a smaller link than two copies.
G/G No 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.
