How Polygenic Testing Works

Polygenic testing evaluates your risk for cancer by analyzing multiple genetic variants, rather than focusing on single gene mutations. It involves collecting a sample of your DNA, usually through a blood or saliva test, which is then sent to a lab. There, advanced algorithms examine thousands of genetic markers associated with cancer risk. Each variant contributes a small amount to your overall risk, and the test combines these data points to generate a risk score. This score helps predict your likelihood of developing certain cancers based on your unique genetic makeup. Unlike single-gene tests, polygenic testing provides a broader view of your inherited risk, capturing the complex interplay of many genes that influence cancer development. It’s a powerful tool for personalized risk assessment. Incorporating top genetic markers enhances the accuracy and comprehensiveness of the risk evaluation.

Key Genetic Variants and Their Impact

Certain genetic variants play a significant role in determining your cancer risk by influencing how cells grow, divide, and repair themselves. These variants, often found in specific genes, can increase susceptibility to certain types of cancer. For example, mutations in tumor suppressor genes impair cell cycle regulation, leading to uncontrolled growth. Variants in DNA repair genes can reduce the body’s ability to fix genetic damage, raising cancer chances. Additionally, some variants affect hormone levels or immune responses, impacting cancer development. Understanding these key variants helps identify your risk factors more accurately. Brewing methods can influence the detection of genetic mutations related to cancer susceptibility.

Interpreting Polygenic Risk Scores

Interpreting polygenic risk scores involves understanding how multiple genetic variants collectively influence your likelihood of developing cancer.
