SERPINF2 Gene
Serpin Family F Member 2 (SERPINF2) is a gene involved in fibrinolysis that has been studied in relation to immune function, metabolism, and chronic illness. Variants in SERPINF2 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the SERPINF2 gene?
SERPINF2 encodes serpin family f member 2, a protein involved in fibrinolysis. It belongs to the Coagulation category and is part of the Coagulation & Vascular biological cluster. SERPINF2 (α2-antiplasmin) is the primary plasmin inhibitor in plasma, rapidly inactivating free plasmin to regulate fibrinolysis. Elevated α2-antiplasmin causes impaired fibrinolysis and hypofibrinolysis.
Biological role and pathway
SERPINF2 is involved in the fibrinolysis pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Coagulation & Vascular cluster work together to maintain balanced function across interconnected biological systems.
Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.
SERPINF2 and Long COVID / ME-CFS research
α2-antiplasmin-plasmin balance determines net fibrinolytic activity. Elevated SERPINF2 or variants increasing α2-antiplasmin activity may contribute to the hypofibrinolysis and resistance to fibrin dissolution documented in Long COVID microthrombi.

Frequently asked questions
What is the SERPINF2 gene and what does it do?
SERPINF2 (Serpin Family F Member 2) is involved in fibrinolysis. SERPINF2 (α2-antiplasmin) is the primary plasmin inhibitor in plasma, rapidly inactivating free plasmin to regulate fibrinolysis. Elevated α2-antiplasmin causes impaired fibrinolysis and hypofibrinolysis.
How may SERPINF2 gene variants relate to Long COVID or ME/CFS?
α2-antiplasmin-plasmin balance determines net fibrinolytic activity. Elevated SERPINF2 or variants increasing α2-antiplasmin activity may contribute to the hypofibrinolysis and resistance to fibrin dissolution documented in Long COVID microthrombi.
