ה BRCA2 gene provides instructions for making a protein that acts as a tumour suppressor. Tumour suppressor proteins help prevent cells from growing and dividing too rapidly or in an uncontrolled way.
Normal function
ה BRCA2 gene provides instructions for making a protein that acts as a tumour suppressor. Tumour suppressor proteins help prevent cells from growing and dividing too rapidly or in an uncontrolled way.
The BRCA2 protein is involved in repairing damaged DNA. In the nucleus of many types of normal cells, the BRCA2 protein interacts with several other proteins to mend breaks in DNA. These breaks can be caused by natural and medical radiation or other environmental exposures, and they also occur when chromosomes exchange genetic material in preparation for cell division. By helping to repair DNA, the BRCA2 protein plays a critical role in maintaining the stability of a cell's genetic information.
Researchers suspect that the BRCA2 protein has additional functions within cells. For example, the protein may help regulate cytokinesis, which is the step in cell division when the fluid surrounding the nucleus (the cytoplasm) divides to form two separate cells. Researchers are investigating the protein's other potential activities.

גנים BRCA
There are a few known gene changes (mutations) that can increase ה risk of certain cancers, and tests available for some of them, including BRCA1 and BRCA2 gene mutations. The BRCA1 and BRCA2 genes normally protect against certain cancers, particularly breast cancer and ovarian cancer. If there is a mutation in one of these genes then this may.

סרטן השד אצל גברים
מהו breast cancer. Family history. Some breast cancers are caused by a flawed gene. The main gene which can cause men to be more at risk of breast cancer is the BRCA2 gene. If two or more of your close family have developed breast cancer, particularly if they had it under the age of 50, you may also be at risk of breast cancer. For example, if.

עובדות על סרטן השד וגורמי סיכון
There are three genes that have been identified that may be faulty. The fault is also called a mutation. When they are faulty, they are particularly associated with breast cancer. These are the BRCA1, the BRCA2 and the TP53 gene mutations. If you carry one or more of these mutations you have an increased risk of developing breast cancer (and.

Some women, trans men and non-binary people are referred for genetic testing if a faulty gene is suspected on the basis of a strong family history of certain cancers. The most common genes are BRCA1 ו BRCA2. For example, if you have two or more close relatives who have had ovarian or breast cancer at a young age (or certain other cancers), you.
