RUNX1 · rs74848904
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
Its strongest genetic-study result is p = 10−13, with 1 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 43,148 European ancestry individuals; replicated in 1,179 Central or South Asian individuals, 1,161 African ancestry individuals.
The effect Each copy of the A allele shifted the measure 0.467 higher (95% confidence interval 0.35-0.59); p = 4 × 10−14.
How common The A allele had a frequency of about 10% in the people studied.
Where it sits Chromosome 21, band 21q22.12 — in a regulatory region of RUNX1.
rs74848904 is a single position in the genome, in or near the RUNX1 gene. Published research associates it with retinal thickness (pixel 60_248). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
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.
