The GTF2I gene provides instructions for making two proteins, TFII-I and BAP-135. TFII-I attaches (binds) to specific areas of DNA and helps regulate the activity of other genes. Based on this role, TFII-I is called a transcription factor. This protein is active in the brain and many other tissues in the body. Studies suggest that the TFII-I protein is involved in coordinating cell growth and division, and it may also play a role in controlling the flow of calcium into cells. Studies show it may be important in a process called myelination, which is the formation of the protective coating around nerve cells called the myelin sheath. This coating insulates nerve cells and promotes the rapid transmission of nerve impulses.

Less is known about BAP-135, the other protein produced from the GTF2I gene. The protein is active in B cells, which are a specialized type of white blood cell that protects the body against infection. When a B cell senses a foreign substance (such as a virus), it triggers a series of chemical reactions that instruct the cell to mature, divide, and produce specific proteins called antibodies to fight the infection. The BAP-135 protein is turned on as part of this series of chemical reactions.

Test de sperme
A sperm test (semen analysis) is usually advised if a couple is having difficulty becoming pregnant (conceiving). The aim is to see if the semen and sperm made by the male partner are normal or not. A semen analysis will also be requested following a vasectomy, as it is the only way a man can be completely certain that he is sterile after this.

Most cases of breast cancer occur by chance. However, breast cancer does occur more often than usual in some families because of their genetic makeup. Most cases of breast cancer occur by chance.

Angioplastie coronarienne
This image shows how an angioplasty and stent placement is performed. How safe is a coronary angioplasty. A coronary angioplasty is a commonly-used procedure, and is a safer alternative to heart surgery for treating blockages in the coronary arteries. Coronary angioplasties do, though, have risks. How likely these risks are to happen differs from.
