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
1 / 4
Its strongest genetic-study result is p = 10−8, with 1 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 91,462 European ancestry individuals; replicated in 30,062 European ancestry individuals, 7,964 African American individuals.
The effect
Each copy of the A allele shifted the measure 0.03 lower (95% confidence interval 0.01-0.05); p = 3 × 10−8.
How common The A allele had a frequency of about 54% in the people studied.
Where it sits Chromosome 17, band 17q11.2 — in an intron of EFCAB5.

The share of all copies of this position that are each version. Source: the population studies published in dbSNP (US NCBI); each row names its study.
What each result means
A/ATwo copies of the version the research linked to Coffee consumption (cups per day). That is the strongest link of the three results. A link in a study is not a diagnosis.
A/GOne copy of the version the research linked to Coffee consumption (cups per day). That is a smaller link than two copies.
G/GNo copy of the version the research linked to Coffee consumption (cups per day). This is the starting point the study compared everyone against.
rs9902453 is a single position in the genome, in or near the EFCAB5 gene. Published research associates it with coffee consumption (cups per day). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs9902453 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 rs9902453 come from?
GWAS Catalog, Mol Psychiatry 2014, PMID:25288136. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
