The TREX1 gene provides instructions for making the three prime repair exonuclease 1 enzyme. This enzyme is a DNA exonuclease, which means that it trims molecules of DNA by removing DNA building blocks (nucleotides) from the ends.
Normal function
The TREX1 gene provides instructions for making the three prime repair exonuclease 1 enzyme. This enzyme is a DNA exonuclease, which means that it trims molecules of DNA by removing DNA building blocks (nucleotides) from the ends.
The three prime repair exonuclease 1 enzyme is helps remove incorrect or damaged nucleotides from DNA. These DNA fragments are created during cell division, DNA repair, cell death (apoptosis), and other processes. The removal of these nucleotides creates even DNA ends, which are necessary for maintaining the stability of genetic material.
Unusual pieces of DNA may be mistaken by cells for the genetic material of viral invaders, triggering immune system reactions. The three prime repair exonuclease 1 enzyme removes pieces of DNA that might otherwise set off an immune response.

Caries dentaires
Caries dentaires (dental caries) is the destruction of tooth tissue by the action of cariogenic bacteria. These are germs that cause dental caries. Almost as soon as teeth erupt through the gums, germs from the mouth will attach to them and multiply. If left undisturbed they will soon form a sticky white layer of bacteria, called dental plaque, on the.

Coarctation de l'aorte
. Blood cannot pass as easily through the narrowed part of the aorta. This means that the blood supply to the lower half of the body can be affected (less blood is able to get through). Also, because of the narrowing, the heart works harder to pump and try to squeeze blood through the narrowing. Because the heart is working harder to pump, this.

Régurgitation mitrale
The mitral valve is a heart valve that lies between the left atrium et left ventricle. What is mitral regurgitation. Mitral regurgitation is sometimes called mitral insufficiency or mitral incompetence. In mitral regurgitation the valve does not close properly. This causes blood to leak back (regurgitate) into the left atrium when the left.
