The first place to look for a leak in a modern car is the fuel tank vent hose or the fuel injection line. Older cars, pre-1980âs, have a carburetor float bowl. When you shut off a pre-1980 car there is normally some boiled fuel that will create a smell of gas.
PROTHROMBIN GENE MUTATION Prothrombin gene mutation is the second most common cause of inherited thrombophilia in the United States. It is present in about 2% of Caucasians. It is caused by a cha nge or mutation in the gene for the blood clotting protein called prothrombin (which is also called Factor II).People with the prothrombin gene mutation have higher than normal levels of prothrombin in their blood, making them prone to blood clots, most common in the veins.t is caused by a cha nge or mutation in the gene for the blood clotting protein called prothrombin (which is also called Factor II).

The Prothrombin Mutation. The prothrombin mutation is the second most common genetic clotting disorder. Almost all children with the prothrombin mutation have one gene (a characteristic passed down from a childâs parent or parents) that is affected. It is uncommon for a child to have both genes affected by the mutation. gene is a characteristic that is passed down from a childâs parent(s). It is rare for a child to have both genes affected. Factor V is a protein that helps form blood clots, a plug that help stop bleeding. With factor V Leiden a childâs body cannot turn off factor V. As a result, too much blood clotting can happen.
