Genetic Testing
NTHL1 Gene Familial Adenomatous Polyposis Type 3 Genetic Test
The NTHL1 Gene Familial Adenomatous Polyposis Type 3 Genetic Test uses Next Generation Sequencing (NGS) to identify mutations in the NTHL1 gene, which are associated with an increased risk of developing certain cancers, particularly colorectal cancer. Genetic counseling is recommended before testing.

Start with fit
Is this the right test for you?
The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.
- ✓Family history of adenomatous polyposis
- ✓Family history of colorectal cancer, especially early-onset
- ✓Presence of multiple colorectal polyps
- ✓Personal history of Familial Adenomatous Polyposis (FAP)
- ✓Unexplained gastrointestinal symptoms in individuals with relevant family history
- ✓Individuals considering prophylactic surgery due to high risk
In plain language
What this test helps you understand
This genetic test specifically looks for mutations in the NTHL1 gene, which are known to be associated with familial adenomatous polyposis type 3. By examining your genetic material, the test can help identify if you have an increased risk for developing certain types of cancers, especially colorectal cancer.
Individuals with a family history of adenomatous polyposis or colorectal cancer, particularly those diagnosed at a young age, may benefit from this test. Other reasons to consider testing include the presence of multiple polyps in the colon or unexplained gastrointestinal symptoms. A personal history of FAP or related syndromes is also an indication for testing.
Taking this test can offer several advantages, including early identification of a genetic predisposition to cancer, enabling informed decisions about surveillance and preventive measures. It can provide peace of mind and guide tailored management strategies developed with your healthcare provider.
Results will indicate whether mutations in the NTHL1 gene were detected. It is crucial to discuss these results with a qualified healthcare provider or genetic counselor to understand their implications and determine appropriate next steps, such as increased surveillance or preventive strategies.
