BRCA single gene testing

BRCA single gene testing is a procedure that identifies mutations in specific genes, BRCA1 or BRCA2, responsible for DNA repair and maintaining the stability of genetic material in cells. Mutations in these genes significantly increase the risk of developing certain types of cancer, most commonly breast and ovarian cancer.

Who conducts BRCA testing?

Specialized medical facilities and genetic counselors lead the process of BRCA testing. The testing involves taking a sample of blood or saliva, which is analyzed in laboratories with appropriate accreditation for genetic analysis, such as the IntroLab laboratory in Belgrade. This approach ensures a high degree of reliability in the results. Genetic counselors play a crucial role in interpreting results, providing support, and advising patients on possible steps after testing.

Who is BRCA single gene testing intended for?

BRCA testing is recommended for individuals with a family history of cancer, especially if there have been cases of breast or ovarian cancer in the family. It is also advised for women who have been diagnosed with breast cancer at a young age. Genetic counseling before testing helps understand potential outcomes and prevention strategies. Additionally, the test is recommended for men with a family history of breast, prostate, or ovarian cancer, as they too can be carriers of mutations.

What makes the BRCA test unique?

The uniqueness of the BRCA test lies in its ability to precisely identify genetic variants that can increase the risk of cancer. This allows individuals to take proactive steps to reduce risk, including preventive surgeries or enhanced medical monitoring. The test can also assist in family planning and decisions about genetic counseling for offspring.

Interpreting results

The results of testing can be positive, negative, or indeterminate. A positive result indicates the presence of a mutation and an increased risk of cancer, while a negative result shows the absence of known mutations. Indeterminate results require further analysis and counseling to clarify their significance. It’s important to note that a negative result does not eliminate the risk of cancer but reduces the likelihood that the risk is hereditary.

In conclusion, BRCA single gene testing is an important tool in cancer prevention, enabling those at increased risk to make informed decisions about their health strategies. Expert guidance and interpretation of results are key to effectively managing risks associated with genetic predispositions.
