What is a prothrombin gene mutation? it is something worth worrying about whether you have it or not?

PGM: Prothrombin gene mutation is an inherited coagulopathy. This means that if you have this gene mutation, you can be at increased risk of forming clots in certain veins in your body. These clots can be dangerous and even lead to death. We do not routinely check for this mutation but do order this test if a young patient develops a deep blood clot.
