F5 Phenotype details

What F5 Phenotype shows

The F5 gene provides instructions for making clotting factor V, a protein that helps blood clot. A common variant called Factor V Leiden makes factor V harder for the body to switch off, which can increase the tendency to form blood clots. This phenotype result translates your F5 genotype into a plain summary, for example whether you carry no copies, one copy or two copies of the variant. It can help explain a personal or family history of blood clots and inform decisions involving clot risk, such as with certain hormone medicines. It reflects a lifelong genetic variant, not a level that changes, and is interpreted alongside your history.
