PLG · rs4252129
Where this position leads
Condition: Fibrinogen and Blood Clotting
What the study found
Who was studied up to 3,244 European ancestry individuals.
The effect Each copy of the T allele shifted the measure 0.159 lower (95% confidence interval 0.13-0.19); p = 2 × 10−26.
How common The T allele had a frequency of about 2% in the people studied.
Where it sits Chromosome 6, band 6q26 — a missense change in PLG.

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.
rs4252129 is a single position in the genome, in or near the PLG gene. Published research associates it with plasma plasminogen levels. 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 Fibrinogen and Blood Clotting. The research behind each link, and its sources, are set out on that condition page.
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.
