Why undergoing this examination?

Most gastrointestinal cancers are sporadic, but approximately 30% have a familial relationship and about 5-10% are hereditary. The study of genes related to different types of gastrointestinal cancer can determine its hereditary character and prevent its development or detect it in its early stages.

What is this exam?

The ColonPLUS test consists of analysis of the patient’s DNA by sequencing NGS (Next Generation Sequencing) of 16 genes related to hereditary gastrointestinal cancer and by MLPA (Multiple Ligation Probe Amplification) of APC, EPCAM, MLH1, MSH2, MSH6 and PMS2 genes for the detection of large deletions and duplications.

For whom is it indicated?

Indicated for the following cases:
• Gastrointestinal cancer before the age of 50.
• Multiple cancers in an individual.
• ≥3 members of a family with gastrointestinal cancer and (uterus and ovary).
• ≥10 gastrointestinal polyps throughout life.
• Family history of hereditary colorectal cancer syndromes.
• Patients who wish to know their genetic risk for gastrointestinal cancer.


Next generation sequencing (NGS) and Multiple Ligation Probe Amplification (MLPA)


• Guaranteed from the experience of the Synlab group, the absolute European leader in laboratory diagnosis. 
Complete genetic study of genes related to hereditary gastrointestinal cancer.
• Free genetic counselling available according to each client needs.
• The changes found are searched in the most complete and updated databases (Free the data).
• Any pathogenic mutation of uncertain significance is confirmed from a new DNA extraction and sequenced again by Sanger which also guarantees 100% coverage of all DNA-readable bases.
