What is the breast cancer gene? The development of breast cancer (mamma carcinoma) can have many different causes. In some cases it can be traced back to a gene mutation. However, it is assumed that only 5-10% of breast cancer cases are based on a hereditary genetic cause. In this case one speaks of hereditary … The breast cancer gene
What does it mean for me if I have this gene? As mentioned above, women with a positive family history should be closely monitored and possibly tested. Before deciding on a molecular genetic diagnosis, the pros and cons should be weighed up and the limits of the diagnosis and possible consequences should be considered. It … What does it mean for me if I have this gene? | The breast cancer gene
How is the breast cancer gene inherited? The inheritance of the BRCA-1 and BRCA-2 mutation is subject to a so-called autosomal dominant inheritance. This means that the BRCA mutation present in one parent is passed on to the offspring with a 50% probability. This occurs independently of gender and can also be inherited from the … How is the breast cancer gene inherited? | The breast cancer gene
What is a BRCA mutation? The BRCA gene (Breast Cancer gene) encodes a tumour suppressor gene in a healthy state. This is a protein that suppresses the uncontrolled division of cells and thus prevents malignant degeneration of the cell into a tumour. If a mutation occurs in this gene, the affected BRCA gene carriers have … BRCA mutation
What are the chances of getting breast cancer? The majority of all breast cancers are not due to genetic changes in the BRCA genes. Studies have shown that only about 5-10% of all breast cancers are inherited through BRCA mutations. Nevertheless, women whose families have a high incidence of breast cancer are uncertain and wonder … What are the chances of getting breast cancer? | BRCA mutation
These tests exist A genetic test is performed in the laboratory, in which a blood sample is examined for mutations in the BRCA1 and BRCA2 genes. A genetic test is a molecular biological examination in which the genetic material is analysed. For women who are considered to have a family history of breast and/or ovarian … These tests exist | BRCA mutation
How can the diagnosis be made? The diagnosis of a BRCA mutation is made by means of a genetic test in which the two genes are examined by means of genetic diagnostics. A genetic test only makes sense if a hereditary predisposition due to a family history of breast or ovarian cancer is probable in … How can the diagnosis be made? | BRCA mutation
Which other tumors are associated with a BRCA mutation? The BRCA genes encode proteins that normally prevent the cell from growing excessively and dividing uncontrollably. Changes in these genes mean that this is no longer guaranteed and cancer develops. Preferably, these are tumours located in the breast or ovaries, but there are also other cancers … Which other tumors are associated with a BRCA mutation? | BRCA mutation
