What is PLG – rs4252120 and Why Does the Cardio Zoomer Test for It?

Plasminogen gene variant

PLG – rs4252120 is a common single‑nucleotide variant near the plasminogen (PLG) gene, which encodes the precursor to plasmin, an enzyme involved in clot breakdown and tissue remodeling. Testing this variant helps explain individual differences in fibrinolysis and vascular repair when viewed with other cardiovascular markers.

About PLG – rs4252120

Overview and History

PLG encodes plasminogen, a serine‑protease zymogen that is converted to plasmin to cleave fibrin and remodel extracellular matrix. The PLG locus sits on chromosome 6; rs4252120 is a single‑nucleotide polymorphism in or near this locus that has been observed in population genetic studies. Researchers have studied rs4252120 and neighboring variants for associations with measures of fibrinolytic activity, wound healing, and vascular biology. While a single variant does not determine function on its own, patterns of variation at PLG can help explain differences in how the body clears clots, remodels vessels, and regulates related inflammatory signals.

Interpreting Highs and Lows

Alleles at rs4252120 that associate with higher plasminogen expression or activity may correspond with increased fibrin breakdown and greater proteolytic remodeling of tissues; this can show up as differences in clot‑related biomarkers and inflammatory markers. Conversely, alleles linked to lower plasminogen activity may correspond with slower fibrin clearance and altered tissue repair dynamics. Interpretation requires integration with the Cardio Zoomer panel—clotting markers, endothelial function tests, lipid patterns, and inflammatory measures all clarify whether a genetic signal is likely to be clinically relevant.

Featured Test

PLG – rs4252120 is included in Cardio Zoomer to add genetic context for fibrinolysis and vascular remodeling. When combined with clotting, endothelial, and inflammatory markers, this variant helps clinicians interpret individual patterns of clot breakdown, healing, and cardiovascular risk biology more precisely.

PLG – rs4252120 FAQs

What is PLG – rs4252120 and why is it important?

PLG – rs4252120 is a common genetic variant located at or near the plasminogen gene. Plasminogen is the precursor to plasmin, the enzyme that helps break down fibrin and remodel tissue. This variant can help explain individual differences in clot breakdown and vascular repair when viewed alongside other tests.

What does it mean if my PLG – rs4252120 levels are low?

If your rs4252120 result is associated with lower plasminogen activity in studies, it may suggest a tendency toward slower fibrin clearance and altered tissue remodeling. That pattern can influence clotting and inflammatory biomarkers, but it needs to be interpreted with the full Cardio Zoomer profile and clinical context.

What does it mean if my PLG – rs4252120 levels are high?

If the variant you carry is associated with higher plasminogen activity, it may be linked to faster fibrin breakdown and increased proteolytic remodeling. Elevated genetic association alone doesn’t define risk—correlating with clotting, endothelial, and inflammatory markers helps determine its likely clinical relevance.

Why is PLG – rs4252120 included in the Cardio Zoomer?

This variant helps characterize the fibrinolytic side of cardiovascular biology, adding genetic insight into clot breakdown, vessel remodeling, and inflammation. Combined with biochemical and imaging markers in Cardio Zoomer, it supports more precise pattern recognition and personalized interpretation of cardiovascular risk drivers.
