The PIGT gene provides instructions for making a protein called GPI transamidase component PIG-T (shortened to PIG-T protein). This protein is important for the attachment of certain proteins to the cell surface. Specifically, the PIG-T protein attaches (binds) a molecule called a glycosylphosphatidylinositol (GPI) anchor to various proteins inside the cell. After the GPI anchor and protein are bound, the anchor is attached to the outer surface of the cell membrane. Anchored proteins have a variety of roles, including sticking cells to one another, relaying signals into cells, and protecting cells from destruction.

Cushing's syndrome
Cushing's syndrome is caused by too high a level of glucocorticoid in the body. This can be caused by taking steroid medication long-term (the common cause) or by the body making too much cortisol (the main glucocorticoid made by the body). Symptoms usually develop gradually and so the diagnosis (other than that caused by steroid medication) may.

Mitral stenosis
Mitral stenosis means that when the mitral valve opens, it does not open fully. The opening is therefore narrower than normal (stenosed). The mitral valve is a heart valve that lies between the left atrium and left ventricle. The valve has two flaps (cusps). The valve allows blood to flow into the left ventricle when the left atrium squeezes.

Obsessive-compulsive disorder
Obsessive-compulsive disorder (OCD) is a condition where you have recurring obsessions, compulsions, or both. The usual treatments are cognitive behavioural therapy (CBT), a selective serotonin reuptake inhibitor (SSRI) antidepressant medicine, or both. Treatment often works well to reduce the symptoms and distress of OCD greatly. What is OCD..
