Where this position leads
Condition: Blood Cell Counts
Strength of the evidence
Its strongest genetic-study result is p = 10−14, 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 153,950 Korean ancestry individuals.
The effect Each copy of the A allele shifted the measure 0.0224 higher (95% confidence interval 0.017-0.028); p = 2 × 10−14.
How common The A allele had a frequency of about 30% in the people studied.
Where it sits Chromosome 9, band 9p24.1 — in an intron of RCL1.
rs7870674 is a single position in the genome, in or near the RCL1 gene. Published research associates it with mean corpuscular hemoglobin. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Blood Cell Counts. The research behind each link, and its sources, are set out on that condition page.
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.
