What the study found

Who was studied 394,626 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.15 higher (95% confidence interval 0.11-0.19); p = 6 × 10−25.

How common The T allele had a frequency of about 63% in the people studied.

Where it sits Chromosome 6, band 6p21.32 — between genes, 7 kb from HLA-DRB9.

What each result means

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

Questions about rs9391884

What is rs9391884?

rs9391884 is a single position in the genome, in or near the near HLA-DRB9 gene. Published research associates it with psoriasis. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs9391884 linked to?

On MyGeneLog this position is linked to Psoriasis. The research behind each link, and its sources, are set out on that condition page.

Does having rs9391884 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 rs9391884 come from?

GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
