Stands on its own.
Nothing else here links to this position yet — but the page above is the point: what the
research found, what each genotype means, and where it came from, in language you can
read. Links to conditions, drugs and the senses appear automatically if we write them.
Strength of the evidence
2 / 4
Its strongest genetic-study result is p = 10−22, with 2 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 51,802 African American or Afro-Caribbean cases, 63,903 African American or Afro-Caribbean controls, 22,361 Hispanic or Latin American cases, 35,203 Hispanic or Latin American controls, 2,276 East Asian ancestry cases, 4,318 East Asian ancestry controls, 154,958 European ancestry cases, 276,347 European ancestry controls.
The effect
Each copy of the G allele shifted the measure 0.0672 higher (95% confidence interval 0.053-0.082); p = 2 × 10−22.
How common The G allele had a frequency of about 87% in the people studied.
Where it sits Chromosome 3, band 3p25.2 — in an intron of PPARG.
What each result means
A/ANo copy of the version the research linked to Diabetes mellitus (PheCode 250). This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to Diabetes mellitus (PheCode 250). That is a smaller link than two copies.
G/GTwo copies of the version the research linked to Diabetes mellitus (PheCode 250). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs2197423
What is rs2197423?
rs2197423 is a single position in the genome, in or near the PPARG gene. Published research associates it with diabetes mellitus (phecode 250). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs2197423 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 rs2197423 come from?
GWAS Catalog, Science (New York, N.Y.) 2024, PMID:39024449. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
