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).

A mutation is a change in the base sequence of DNA that can affect the structure and function of proteins when they occur within a gene. Mutations can be spontaneously caused by copying errors during DNA replication or induced by exposure to external elements such as chemical mutagens, radiation or viruses. Cystic fibrosis is an example of a disease which can result from a nonsense mutation (this may not be the only cause though). 2  Frameshift mutations occur when the addition or removal of a base alters the reading frame of the gene.
