You've watched this disease in your family. Now you're asking whether it's in your future — and that question deserves more than uncertainty.
Whole genome sequencing reveals your APOE status, screens for early-onset familial variants, and contextualizes your dementia risk within a complete genetic picture.
Alzheimer's & Dementia Risk
Alzheimer's disease is the most common cause of dementia, accounting for 50–60% of all dementia cases and affecting over 50 million people worldwide. Two distinct genetic forms exist: early-onset familial AD (less than 65 years, ~5–10% of all cases) caused by highly penetrant autosomal dominant variants in PSEN1, PSEN2, or APP, with onset sometimes as early as the 30s; and late-onset AD (over 65 years, ~90% of cases), which has a complex genetic architecture. APOE ε4 is the most significant known genetic risk factor for late-onset disease, but the presence of APOE ε4 influences risk — it does not predict or cause Alzheimer's.
APOE ε4 status modulates lifetime dementia risk significantly: carrying one copy of APOE ε4 doubles to triples risk compared to ε3/ε3 genotype; carrying two copies increases risk 8–12-fold. First-degree relatives of people with Alzheimer's disease have a cumulative lifetime dementia risk of 20–25% compared to approximately 10% in the general population. However, many ε4 carriers never develop dementia, and many people without ε4 do develop Alzheimer's disease — genetics influences but does not determine outcome.
Early-onset familial disease caused by PSEN1 or PSEN2 pathogenic variants follows autosomal dominant inheritance with ~100% penetrance — a diagnosis is definitive. For late-onset disease, APOE status alone provides incomplete information. APOE ε4 results require careful genetic counseling context because the risk is probabilistic, not deterministic. A genetic diagnosis enables enrollment in prevention trials, informed decision-making about lifestyle modifications, and reproductive counseling. Understanding your genetic status enables personalized prevention strategies before symptoms appear.
APOE testing alone misses early-onset variants and hundreds of risk loci. Genome Test captures the full genetic picture of dementia risk.
APOE testing alone leaves you with an incomplete picture
Direct-to-consumer APOE genotyping provides a single data point without clinical context. APOE ε4 testing does not detect the dozens of additional genetic loci identified by GWAS studies that collectively contribute to dementia risk, nor does it capture protective variants in APOE itself (e.g., the Christchurch variant, APOE ε3-R136S, which appears protective). For families with early-onset Alzheimer's, APOE testing entirely misses pathogenic variants in PSEN1, PSEN2, or APP that cause highly penetrant familial disease. Whole genome sequencing captures APOE genotype, complete PSEN1/PSEN2 sequencing, and all GWAS loci — enabling polygenic risk scoring far more predictive than APOE alone.
A genetic finding enables prevention and eligibility for emerging therapies
A pathogenic PSEN1 or PSEN2 variant confirms early-onset familial Alzheimer's and enables presymptomatic testing of at-risk relatives, enrollment in prevention trials like DIAN-TU, and reproductive counseling. APOE ε4 status informs prevention-oriented decisions: cardiovascular health optimization, cognitive engagement, exercise, and medication choices. For example, APOE ε4 homozygotes have higher risk of amyloid-related imaging abnormalities (ARIA) with anti-amyloid therapies like lecanemab, which guides dosing and monitoring decisions. Genetic status transforms dementia from an uncontrollable inheritance into a modifiable risk.
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.
Learn more →Your diagnosis may be right. Your treatment plan may be incomplete.
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.

Some people don't wait for a diagnosis or a family history to act. Whole genome sequencing gives you the complete genetic picture now — so you and your doctor can make informed decisions before anything becomes urgent.

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.
