factor V




One of the blood proteins that maintains the balance between the blood clotting too easily or too slowly after an injury. About 5% of the population have an inherited mutation in the gene controlling factor V production, known as factor V Leiden. They are at increased risk of deep-vein thrombosis, particularly if taking the oral contraceptive pill or going on long aircraft journeys.
