A New Way to Test for Lynch Syndrome
Simplify the path to diagnosis with reliable Lynch syndrome testing. Lynsight’s assay, DiagMMR, tests for mismatch repair deficiency(MMR), giving providers and patients a clear picture about the presence of LS.
Tumor studies & DNA sequencing
Genetic testing has come a long way and is one of the main methods of testing for Lynch syndrome today. Testing typically starts with tumor testing and confirming Lynch syndrome through DNA sequencing. However, this method is limited, introducing challenges for patients, their families, and providers:
Accurate results require knowledge and details of the inherited gene mutation.
Diagnosis requires sophisticated and specialized interpretations.
53%-60%1-3 Lynch syndrome cases are left undiagnosed.
Testing pathways are often limited to the patient with cancer, instead of testing the entire family.
Get answers, not unclear interpretations
with Lynsight’s test, DiagMMR
Suspected but inconclusive Lynch syndrome cases stress the patient, family, and healthcare system with long and expensive interpretations – and often no answer at all. Lynsight simplifies the path to diagnosis with a reliable test that goes directly to the problem: deficient MMR function.
Here’s how it works.
Time from sample to interpreted results: 4 weeks
Step 01
Sample
In a quick and simple procedure, skin biopsies are collected from the inner forearm and dissected within 4 days for primary cell culture.
Time from sample to interpreted results: 4 weeks
Step 02
Cell Culture
Cells are transferred to a cell culture flask in humid conditions for adherence and growth. After 14 days of initial growth, cells are trypsinized and expanded in a subsequent culture to approximately 1 × 10^8 cells.
Time from sample to interpreted results: 4 weeks
Step 02
Repair
Cells are collected and treated with cold isotonic and hypotonic buffers before disrupting cell membranes. Nuclei are centrifuged, and then the extracted protein sample is desalted.
Time from sample to interpreted results: 4 weeks
Step 02
Algorithm
To distinguish between MMR proficiency and deficiency, the functional MMR efficiency is assessed through a series of reactions and analyses. Repair efficiency is measured as a percentage of repaired DNA of the total amount of DNA in each reaction.
Time from sample to interpreted results: 4 weeks
Step 02
Result
The test result is quantitative. Interpretations are done based on at least two independent results to ensure accuracy.
Predictive, not reactive
DiagMMR detects MMR deficiency from a minimally invasive, non-malignant tissue sample – before tumors appear.
Functional test
Lynch syndrome testing is done directly on patient cells. Because we extract proteins from patient cells, we don’t need to know the underlying variant.
Actionable results
While DNA sequencing returns results faster, interpretations can take 6-8 weeks or more. DiagMMR test results are available in 4 weeks and don’t require interpretation – helping patients and families take their next steps faster.
