Hereditary Bladder Cancer — NAT2 slow acetylator genotype increases risk through impaired carcinogen metabolism, and Lynch syndrome (particularly MSH2) includes urinary tract cancer as part of the hereditary cancer spectrum.
Whole genome sequencing evaluates NAT2 acetylator status, Lynch syndrome genes (MSH2 — highest urinary tract cancer risk), GSTM1 deletion, and additional bladder cancer susceptibility variants.
Bladder Cancer — Hereditary
Bladder cancer affects approximately 83,000 Americans annually. While smoking is the dominant environmental risk factor, genetic susceptibility plays a significant role. NAT2 (N-acetyltransferase 2) genotype is the best-established genetic risk factor — slow acetylators (~50-60% of Europeans) have approximately 40% increased bladder cancer risk due to impaired hepatic detoxification of aromatic amine carcinogens (from tobacco smoke and occupational exposures). GSTM1 null genotype (homozygous deletion, ~50% of populations) further impairs carcinogen detoxification and independently increases risk.
Lynch syndrome — particularly MSH2 pathogenic variants — confers elevated risk of upper urinary tract urothelial carcinoma (renal pelvis and ureter cancer). MSH2 carriers have approximately 12-18x increased risk of upper tract urothelial cancer compared to the general population. This association is strong enough that unexplained upper tract urothelial cancer in a patient under 60 should prompt Lynch syndrome evaluation. Lynch-associated urothelial cancers are MSI-high and may respond to immune checkpoint inhibitors (pembrolizumab), similar to Lynch-associated colorectal cancer.
Additional hereditary bladder cancer associations include RB1 (retinoblastoma gene — survivors have elevated bladder cancer risk, possibly related to cyclophosphamide treatment), FGFR3 (germline variants may predispose to low-grade papillary bladder cancer), and emerging GWAS loci that influence urothelial biology and carcinogen susceptibility. Pharmacogenomic NAT2 genotyping has dual utility — assessing bladder cancer risk AND guiding drug metabolism for medications metabolized by NAT2 (isoniazid, hydralazine, sulfonamides).
NAT2 slow acetylators have dual clinical relevance: increased bladder cancer risk AND altered drug metabolism. If you're a slow acetylator who smokes, your bladder cancer risk is substantially elevated — making smoking cessation even more urgent.
NAT2 genotype simultaneously assesses bladder cancer risk and pharmacogenomic drug metabolism. Lynch syndrome (MSH2) bladder cancers respond to immunotherapy. WGS captures both cancer genetics and pharmacogenomics.
NAT2 slow acetylators who smoke have compounded bladder cancer risk — genotype-informed risk counseling enhances smoking cessation motivation
The combination of NAT2 slow acetylator genotype and tobacco smoking produces a multiplicative interaction for bladder cancer risk. Informing a patient that they carry a genetic variant that impairs their ability to detoxify tobacco carcinogens — specifically increasing their bladder cancer risk — provides a powerful personalized motivator for smoking cessation. This pharmacogenomic counseling approach has been shown to enhance cessation motivation in clinical studies.
Unexplained upper tract urothelial cancer should trigger Lynch testing — MSH2 carriers have immunotherapy-responsive tumors
Upper tract urothelial carcinoma (renal pelvis, ureter) in a patient under 60 without obvious risk factors should prompt MSH2/Lynch syndrome evaluation. Lynch-associated urothelial cancers are MSI-high and respond to pembrolizumab. Additionally, Lynch diagnosis triggers cascade family testing and cancer surveillance protocols that prevent colorectal, endometrial, and other Lynch-associated cancers in family members.
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.

Standard diagnostic tests check for a pre-selected set of answers. We sequence your full DNA — including parts that no test was designed to check. If the answer is in your genome, we will help you find it.

Your genes determine which treatments are most likely to work — and which are not. We give your doctor the tools and insights to inform your treatment plan.

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.
