Where this position leads
Condition: Psoriasis
What the study found
Who was studied 3,496 European ancestry cases, 5,186 European ancestry controls, 1,588 Chinese ancestry cases, 3,546 Chinese ancestry controls; replicated in 5,134 European ancestry cases, 5,633 European ancestry controls, 5,151 Chinese ancestry cases, 5,152 Chinese ancestry controls.
The effect Each copy of the T allele carried 1.30 times the odds of Psoriasis (95% confidence interval 1.22-1.37); p = 1 × 10−18.
How common The T allele had a frequency of about 27% in the people studied.
Where it sits Chromosome 2, band 2q24.2 — a missense change in IFIH1.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
What people read about alongside this
Papers in Europe PMC whose title or abstract names both this rsID and that subject. A shared paper means somebody wrote about the two together — it is not a claim that this position explains the subject.
rs3747517 is a single position in the genome, in or near the IFIH1 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.
On MyGeneLog this position is linked to Psoriasis. The research behind each link, and its sources, are set out on that condition page.
Subjects that appear in the title or abstract of the same papers as this rsID include infection and immunity (2 papers). A shared paper means somebody wrote about the two together; it is not a claim that this position explains the topic.
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.
