Factor V Leiden as named after the Dutch city Leiden in which it was discovered. Factor V Leiden is a genetic blood clotting disorder that results from a mutation of the Factor V gene. Most of the time you will inherit Factor V Leiden from your family. If kept under control blood clots are mostly harmless but if left uncared you can have a piece of the blood clot break and enter your lung there it will cause serious damage like a heart attack or stroke. The main job for our blood is to transport important nutrients and oxygen to all the body tissue.
