What is a genetic test? A genetic test describes an analysis of human DNA. The DNA is the carrier of the genetic material and is located in the cell nucleus, where it can be isolated by specific procedures. The DNA can then be examined. The smallest mutations can influence gene expression and have health consequences. … The genetic examination
What genetic tests for hereditary diseases are available? The principle of every genetic examination is DNA sequencing. Here, the DNA is broken down into its building blocks, the gene section to be examined is multiplied and then analyzed. Basically, a distinction can be made between genetic examinations that take place before birth (prenatal diagnostics) and … What genetic tests for hereditary diseases are available? | The genetic examination
The preparation for the examination The preparation for the examination includes an indication – it must be clearly evident why one wants to do a genetic examination. In addition, the patient should be informed about possible effects and changes in his or her life if the test result is positive. After a certain period of … The preparation for the examination | The genetic examination
The duration of the results The duration of the results can vary greatly. It depends on which test is performed. Blood tests usually take less time than molecular genetic methods because the procedure is more complex. If you want an exact time, you should discuss this with your doctor or the laboratory. How reliable are … The duration of the results | The genetic examination
What are the alternatives? There is no real alternative to genetic testing. If a genetic disease is suspected, only a DNA analysis can provide the necessary information. It can confirm or even rule out the disease. Blood tests or imaging procedures are not an alternative. They can only point the way forward. If genetic diseases … What are the alternatives? | The genetic examination
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
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
