Strength of the evidence

2 / 4

Its strongest genetic-study result is p = 10−34, 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 408,112 British individuals.

The effect Each copy of the C allele shifted the measure 0.0365 higher (95% confidence interval 0.031-0.042); p = 2 × 10−34.

How common The C allele had a frequency of about 50% in the people studied.

Where it sits Chromosome 6, band 6p21.32 — between genes, 2.3 kb from HLA-DQA1.

What each result means

C/C Two copies of the version the research linked to White blood cell count. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/T One copy of the version the research linked to White blood cell count. That is a smaller link than two copies.
T/T No copy of the version the research linked to White blood cell count. This is the starting point the study compared everyone against.

Questions about rs9271737

What is rs9271737?

rs9271737 is a single position in the genome, in or near the HLA-DQA1 gene. Published research associates it with white blood cell count. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs9271737 linked to?

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.

Does having rs9271737 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 rs9271737 come from?

GWAS Catalog, Cell 2020, PMID:32888494. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
