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.
What the study found
Who was studied 5,989 European ancestry cases, 42,891 European ancestry controls.
The effect
Each copy of the T allele carried 1.10 times the odds of COVID-19 (critical illness vs population or mild symptoms) (95% confidence interval 1.09-1.19); p = 3 × 10−9.
How common The T allele had a frequency of about 65% in the people studied.
Where it sits Chromosome 6, band 6p21.32 — between genes, 4.4 kb from HLA-DQA1.
What each result means
C/CNo copy of the version the research linked to COVID-19 (critical illness vs population or mild symptoms). This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to COVID-19 (critical illness vs population or mild symptoms). That is a smaller link than two copies.
T/TTwo copies of the version the research linked to COVID-19 (critical illness vs population or mild symptoms). That is the strongest link of the three results. A link in a study is not a diagnosis.
rs9271609 is a single position in the genome, in or near the near HLA-DQA1 gene. Published research associates it with covid-19 (critical illness vs population or mild symptoms). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
Does having rs9271609 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 rs9271609 come from?
GWAS Catalog, Nature 2022, PMID:35255492. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
