F5

Hematologic System · Coagulation, Fibrin Formation & Fibrinolysis

Is every F5 variant factor V Leiden?

F5 encodes clotting factor V, which helps the body form clots after injury. Factor V Leiden refers to a particular variant, so other F5 findings cannot automatically be given the same interpretation.

Common Gene Name
coagulation factor V
NCBI Gene ID
2153
Chromosome
1
