Molecular genetic testing comprises examination and assessing of the DNA at a molecular level to detect genetic disorders, mutations, and inherited conditions. It helps in identifying hereditary diseases, birth defects, and even cancer risks, giving a clearer picture of your genetic health.
Indications for Molecular Genetic Testing:
● Family history of genetic disorders: If conditions like cystic fibrosis, sickle cell anemia, or hemophilia run in the family, this test can evaluate the risk of the disease.
● Infertility issues: Couples facing unexplained infertility may benefit from genetic testing to uncover potential hereditary factors.
● Cancer risk assessment: Identifying mutations in genes like BRCA1 and BRCA2 can reveal your risk for hereditary breast or ovarian cancer.
● Prenatal screening: Tests such as NIPT (Non-Invasive Prenatal Testing) can detect genetic abnormalities in a fetus.
How Molecular Genetic Testing Works:
● A blood sample or cheek swab is collected to extract your DNA.
● Scientists analyze the DNA to identify specific mutations or abnormalities related to particular genetic conditions.
Interpretation:
● Normal Results: No genetic mutations were found for the conditions tested, indicating no significant risk.
● Abnormal Results: Specific gene mutations linked to conditions like cystic fibrosis, hemochromatosis, Down syndrome, or BRCA-related cancers are detected.
Management Based on Results:
● For genetic disorders: Genetic counseling helps you understand the results and explore treatment options or preventive steps.
● For cancer risks: Early screenings, lifestyle adjustments, and in some cases, preventive measures such as medications or surgeries may be recommended.
Price in India:
● Testing costs typically range from ₹5,000 to ₹20,000, depending on the specific condition or genes being analyzed.
Frequently Asked Questions
How accurate is genetic testing?
Molecular genetic testing is highly reliable for identifying known mutations but cannot predict diseases influenced by multiple factors or unknown genes.
Can it predict all diseases?
No, it only detects specific genetic mutations and cannot predict diseases caused by environmental or non-genetic factors.
Disclaimer: Genetic test results should always be interpreted alongside your medical history and environmental factors for a complete understanding.
