BRCA2 Gene Deletion Duplication Analysis (MLPA)

BRCA2 gene deletion duplication analysis is a genetic test conducted using the Multiplex Ligation-dependent Probe Amplification (MLPA) method. This analysis is used to detect structural changes (such as deletion or duplication) in the BRCA2 gene.

The BRCA2 gene is known to play a role in the development of cancers like breast and ovarian cancer. This test is performed to identify major changes in the BRCA2 gene by detecting the absence (deletion) or excess (duplication) of specific regions of genetic material.

MLPA is a technique used to determine changes in the number of copies in the DNA sequence. This method uses special DNA probes to determine the presence and number of specific regions of genetic material. This analysis method is used to detect whether certain regions of the BRCA2 gene are missing or present in excess.

This test is used to identify structural changes in the BRCA2 gene in individuals, assess cancer risk, and understand genetic predispositions. It is often requested for individuals at risk of breast and ovarian cancer or those with a family history of these cancer types. The results of this test play a significant role in determining cancer risk and planning treatment.

What is BRCA2 Gene Deletion Duplication Analysis Test?

The BRCA2 gene deletion duplication analysis test is a genetic test conducted to detect structural changes in the BRCA2 gene using the Multiplex Ligation-dependent Probe Amplification (MLPA) method. This test aims to identify deficiencies or excess genetic material in specific regions using MLPA. These changes in the BRCA2 gene can increase the risk of cancer, such as breast and ovarian cancer. This test plays a crucial role in evaluating cancer risk and planning appropriate treatment.

When is BRCA2 Gene Deletion Duplication Analysis Test Requested?

1. Family History:

For individuals with a family history of breast cancer, ovarian cancer, or other specific types of cancer.

For individuals where structural changes in the BRCA2 gene are known within the family.

2. Individual Risk Assessment:

To assess high-risk situations based on the individual's personal medical history and risk factors.

In cases where there is a higher risk of cancer, such as breast cancer or ovarian cancer.

3. Genetic Counseling Recommendation:

In recommended tests for cancer risk assessment along with genetic counseling.

4. Previous Cancer Diagnosis:

For individuals previously diagnosed with cancer, such as breast cancer or ovarian cancer.

5. Treatment and Monitoring:

For planning treatment and monitoring strategies after diagnosis.

Changes in the BRCA2 gene can increase the risk of breast cancer, ovarian cancer, and some other types of cancer. Therefore, requesting this test in the mentioned situations can help determine a patient's cancer risk and develop suitable treatment or monitoring strategies. Since each situation and person is different, the decision to request and interpret the test is generally made based on personal and family medical history, risk factors, and genetic counseling results. Therefore, the request and interpretation of the test are usually carried out by a healthcare professional or genetic counselor.
