Colon cancer at 40 doesn't feel random — because it wasn't. Half your family is asking whether it's coming for them, too.
Whole genome sequencing identifies the specific mismatch repair gene variant — giving you and your family the certainty to act on what you inherit before cancer develops.
Lynch Syndrome
Lynch Syndrome is caused by inherited variants in genes that encode proteins of the DNA mismatch repair (MMR) system: MLH1, MSH2, MSH6, and PMS2. These proteins correct errors in DNA replication — when they fail, mutations accumulate unchecked, accelerating tumor formation. The result is a syndrome characterized by lifetime colorectal cancer risk of 40–80%, with endometrial cancer in women being the second most common manifestation.
Approximately 1 in 279 people carry a Lynch Syndrome variant, making it the most common hereditary colorectal cancer syndrome. The two most commonly implicated genes, MLH1 and MSH2, confer the highest cancer risks and the earliest age of onset. MSH6 and PMS2 variants are associated with later onset and lower overall lifetime cancer risk — yet still warrant enhanced surveillance. The syndrome also accounts for 2–5% of all colorectal cancers in the population.
Identifying the specific gene involved has immediate clinical implications. A Lynch variant follows autosomal dominant inheritance, meaning each child of a carrier has a 50% chance of inheritance. Colonoscopy screening every 1–2 years starting at age 20–25 reduces colorectal cancer mortality by approximately 65%. Women qualify for gynecological risk assessment and may elect risk-reducing surgery. For tumors that develop with MSI-high status, immunotherapy (pembrolizumab) produces dramatic responses. One person's genetic finding opens the door to preventive action across the entire family.
Lynch Syndrome is genetically stratifiable: MLH1 and MSH2 carriers have the highest cancer risks with earlier age of onset; MSH6 carriers have later onset with lower lifetime risk; PMS2 carriers have the mildest phenotype — these gene-specific risk profiles guide the intensity of surveillance.
Standard Lynch panels focus on MLH1, MSH2, MSH6, and PMS2 alone. Up to 20% of Lynch families have EPCAM deletions that standard sequencing misses entirely.
Structural variants slip through standard sequencing
Lynch Syndrome can be caused by large deletions in EPCAM (located upstream of MSH2) that silence MSH2 expression through promoter methylation. These rearrangements are not detectable by short-read sequencing panels — they require specialized deletion analysis that most standard tests do not perform. Whole genome sequencing reads the full DNA sequence at sufficient depth to identify structural variants, capturing the full variant landscape in Lynch families.
One result changes cancer prevention for your whole family
Lynch Syndrome variants follow predictable inheritance patterns, enabling cascade testing across families at risk. When a pathogenic MLH1, MSH2, MSH6, or PMS2 variant is identified, first-degree relatives can be offered targeted genetic testing — converting one person's diagnosis into actionable preventive opportunities for siblings, parents, and children. Relatives identified through cascade testing can begin surveillance at age 20–25, potentially preventing cancers before they develop.
Your full DNA (not just a part of it)
Traditional genetic testing looks at narrow sets of genes, missing most parts of your genome. We sequence your full genome — every gene and every region between genes.
Comprehensive insights and specialized reports
Easy to read and with answers you and your doctor can act on. Not a file to interpret — 200+ clinical reports, organized by category.
Your test becomes more valuable every year
Your DNA does not change, but genome science is accelerating. Every month, new variant-disease associations are discovered. We validate these findings and update your reports automatically. Your test becomes more valuable every year.
The results doctors bring to their hardest cases.
Forty years of uncertainty. One test.
A patient had spent decades in the UK healthcare system without a diagnosis. Dante data, accepted by NHS clinical teams at Queen Elizabeth University Hospital Glasgow, identified Noonan Syndrome and a RUNX1 leukemia-associated variant that had gone undetected. After 40 years, they finally had an answer.
A complete read delivers a complete picture.
A patient came to Dante to investigate periodic paralysis. Reading the complete genome identified a concurrent hereditary cardiac finding — Brugada syndrome — that their doctor confirmed with an ECG. The result also explained a family member's unresolved cardiac history. One test. Every answer in it.
Sequenced in 2019. The data worked in 2021.
Jennifer sequenced her genome with Dante two years before her breast cancer diagnosis. When treatment began, Dante's pharmacogenomics data showed her prescribed chemotherapy would cause serious adverse effects. Her doctor selected an alternative — and she started effective treatment from day one.
Every genetic question deserves a complete answer.
Whether you are searching for answers today or protecting your health for tomorrow, a complete read of your entire genome is the only place to start.
It runs in your family. Now you can know if it runs in your genes.
Your genome contains inherited variants associated with medical conditions like cardiac, cancer, and neurological. We read all of them — with the clinical depth to give the result meaning.

Common questions about whole genome sequencing.
What is the difference between whole genome sequencing and a targeted genetic test?
Targeted genetic tests — including standard hereditary cancer panels — read a pre-defined list of known variants in a specific set of genes. They are designed to find what they already know to look for. Whole genome sequencing reads your entire genome: all 6 billion base pairs, every gene, every region between genes. A Mayo Clinic study published in JAMA Oncology found that standard testing guidelines missed more than half of patients with inherited cancer mutations. Genome Test does not have a fixed list.
What will I receive when my results are ready?
Your Dante Genome delivers 200+ physician-ready reports organized by clinical category — hereditary cancer, cardiac conditions, rare diseases, pharmacogenomics, carrier status, and more. Reports are delivered to your secure Genome Manager and are formatted for direct clinical use. Your genome data is permanently retained and re-analyzed automatically as science advances.
What happens if a clinically significant variant is found?
If a pathogenic or likely-pathogenic variant is identified, it will be clearly flagged in your physician-ready report with clinical context, published evidence, and recommended next steps. We recommend sharing any clinically significant finding with your physician or a genetic counselor, who can guide decisions about surveillance, risk reduction, or cascade testing for family members.
How is this different from a consumer DNA test like 23andMe or AncestryDNA?
Consumer DNA tests use genotyping chips that read less than 0.1% of your genome — a tiny pre-selected set of common variants. They are optimized for ancestry and population-level traits, not clinical genetic findings. The Dante Genome Test sequences 100% of your genome at 30X coverage, the same standard used in clinical diagnostic settings. The two tests are not comparable in scope, methodology, or clinical utility.
How long does it take to get results, and how are they delivered?
Your collection kit ships within 48 hours of ordering. Once your sample arrives at our CLIA-certified laboratory, sequencing and analysis takes 6–8 weeks. Results are delivered securely to your Genome Manager, where you can access your reports, share them with your physician, and receive automatic updates as new findings are validated against your genome.
