SelectedGenetic Bowel Cancer Risk | London Blood Tests |
At London Blood Tests, we provide advanced genetic testing services to help you understand and manage your health risks. Our Genetic Bowel Cancer Risk Test screens for genetic variants associated with an increased risk of bowel cancer and Lynch Syndrome. This test provides valuable insights into your genetic predisposition, allowing you to take proactive measures in managing your health.
Our Genetic Bowel Cancer Risk Test screens and detects genetic variants in 11 genes that may increase the risk of bowel cancer and Lynch Syndrome. The genes analyzed include APC, BMPR1A, EPCAM, MLH1, MSH2, MSH6, MUTYH, PMS2, PTEN, SMAD4, and STK11.
1. APC: Tumor suppressor gene involved in controlling cell growth. Mutations cause familial adenomatous polyposis (FAP), leading to a high risk of colon cancer.
2. BMPR1A: Involved in cell growth and development. Mutations can cause juvenile polyposis syndrome, increasing the risk of gastrointestinal cancers.
3. EPCAM: Affects cell adhesion and signaling. Mutations can lead to Lynch syndrome (via MSH2 inactivation), increasing the risk of colon and other cancers.
4. MLH1: Involved in DNA mismatch repair. Mutations cause Lynch syndrome, leading to a higher risk of colorectal and other cancers.
5. MSH2: Another gene involved in DNA mismatch repair. Mutations are a common cause of Lynch syndrome, with increased cancer risks.
6. MSH6: Also involved in DNA mismatch repair. Mutations increase the risk of Lynch syndrome, though typically with a later onset than MLH1 or MSH2 mutations.
7. MUTYH: Involved in DNA repair, specifically fixing oxidative damage. Mutations cause MUTYH-associated polyposis (MAP), increasing colorectal cancer risk.
8. PMS2: A DNA mismatch repair gene. Mutations can cause Lynch syndrome, contributing to a higher risk of colorectal and other cancers.
9. PTEN: Tumor suppressor gene that regulates cell growth. Mutations cause Cowden syndrome, increasing the risk of breast, thyroid, and other cancers.
10. SMAD4: Involved in signal transduction and regulating cell growth. Mutations cause juvenile polyposis syndrome, increasing gastrointestinal cancer risk.
11. STK11: Tumor suppressor gene involved in regulating cell growth. Mutations cause Peutz-Jeghers syndrome, leading to an increased risk of gastrointestinal and other cancers.

WhatsApp UsFollow these guidelines for accurate results
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
