ה SDHAF2 gene provides instructions for making a protein that interacts with the succinate dehydrogenase (SDH) enzyme. The SDHAF2 protein helps a molecule called FAD attach to the SDH enzyme. FAD is called a cofactor because it helps the enzyme carry out its function. The FAD cofactor is required for SDH enzyme activity.
Normal function
ה SDHAF2 gene provides instructions for making a protein that interacts with the succinate dehydrogenase (SDH) enzyme. The SDHAF2 protein helps a molecule called FAD attach to the SDH enzyme. FAD is called a cofactor because it helps the enzyme carry out its function. The FAD cofactor is required for SDH enzyme activity.
The SDH enzyme plays a critical role in mitochondria, which are structures inside cells that convert the energy from food into a form that cells can use. Within mitochondria, the SDH enzyme links two important pathways in energy conversion: the citric acid cycle (or Krebs cycle) and oxidative phosphorylation. As part of the citric acid cycle, the SDH enzyme converts a compound called succinate to another compound called fumarate.
Succinate, the compound on which the SDH enzyme acts, is an oxygen sensor in the cell and can help turn on specific pathways that stimulate cells to grow in a low-oxygen environment (hypoxia). In particular, succinate stabilizes a protein called hypoxia-inducible factor (HIF) by preventing a reaction that would allow HIF to be broken down. HIF controls several important genes involved in cell division and the formation of new blood vessels in a hypoxic environment.
ה SDHAF2 gene is a tumour suppressor, which means it prevents cells from growing and dividing in an uncontrolled way.

בדיקות קרישת דם
בדיקות קרישת דם are used to diagnose and assess bleeding problems and to monitor people who take warfarin or other anticoagulant medicines. You may be advised to have blood clotting tests: If you have a suspected bleeding disorder. For example, if you bleed a lot after cuts, or if you bruise easily. If you have certain liver diseases that can.

How do anticoagulants work. Our blood has a complex system of chemicals in it, which, when activated, cause blood clots to form. This is called the clotting cascade. This is normally a good thing; it's activated if we have an injury, like a bleeding wound. The clotting cascade causes a clot to form, stopping the bleeding. However, some people get.
