Function
The Hereditary Cancer Gene Panel is a specialized genetic test that utilizes Next-Generation Sequencing (NGS) to look for mutations in a specific set of genes (e.g., BRCA1, BRCA2, MLH1, TP53) known to increase the risk of developing certain cancers. Unlike a broad panel, a 'focused' panel targets only the most clinically actionable genes related to a patient's personal or family history.
Why it is Ordered
This test is ordered for individuals who have a strong family history of cancer or who have been diagnosed with cancer at an unusually young age. The goals are:
- To determine if a cancer is hereditary.
- To guide surgical decisions (e.g., bilateral vs. unilateral mastectomy).
- To prompt aggressive screening or prophylactic measures for relatives.
- To qualify patients for specific targeted therapies (e.g., PARP inhibitors).
Associated Conditions
- Hereditary Breast and Ovarian Cancer (HBOC): Linked to BRCA mutations.
- Lynch Syndrome: Increased risk of colorectal and endometrial cancers.
- Li-Fraumeni Syndrome: A rare disorder that greatly increases the risk of developing several types of cancer.

Why Context Matters
Genetic testing results are complex. A 'Variant of Uncertain Significance' (VUS) means a change was found, but it's unknown if it causes cancer. Second opinions from genetic counselors are vital to ensure that a VUS isn't misinterpreted as a 'positive' result, which could lead to unnecessary surgeries.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
