Psoriasis

IL21 · rs13137072

Where this position leads

Condition: Psoriasis

rs13137072 Condition: Psoriasis Psoriasis Condition rs13137072 rs13137072 IL21

What the study found

Who was studied 36,466 European ancestry cases, 458,078 European ancestry controls.

The effect Each copy of the A allele carried 0.92 times the odds of Psoriasis (95% confidence interval 0.89-0.94); p = 3 × 10−12.

Where it sits Chromosome 4, band 4q27 — in an intron of IL21.

What each result means

A/A 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.
A/G One copy of the version the research linked to Psoriasis. That is a smaller link than two copies.
G/G No copy of the version the research linked to Psoriasis. This is the starting point the study compared everyone against.

Questions about rs13137072

What is rs13137072?

rs13137072 is a single position in the genome, in or near the IL21 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 rs13137072 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 rs13137072 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 rs13137072 come from?

GWAS Catalog, Nature communications 2025, PMID:40021644. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
