Your hand trembles — and you're wondering if it's the same disease your parent lived with. Knowing your genetics could unlock a treatment they never had.
Whole genome sequencing identifies monogenic Parkinson's variants and polygenic risk factors, connecting you to precision medicine trials and targeted therapies that didn't exist a generation ago.
Parkinson's Disease Risk
Parkinson's disease is the second most common neurodegenerative disorder, affecting 1–2% of the population over 65 and approximately 4% over 85. It is characterized by progressive motor symptoms (tremor, rigidity, bradykinesia), cognitive changes, and psychiatric features. Approximately 5–10% of PD cases have a clearly monogenic basis — caused by pathogenic variants in single genes with high penetrance. LRRK2 gain-of-function variants, most commonly G2019S, cause the most common monogenic form with age-related penetrance (~30% by age 80). SNCA variants (point mutations and gene multiplications) cause rare, aggressive early-onset disease. GBA variants are the most common genetic risk factor overall, present in 5–20% of PD patients depending on ethnicity (19.6% in Ashkenazi Jewish populations vs. ~5% baseline).
Approximately 25% of overall Parkinson's disease risk is attributed to genetic variation, though most cases are sporadic with complex polygenic contributions. The genetic landscape is heterogeneous, with over 90 GWAS loci identified contributing to disease susceptibility. The three major genes — LRRK2, SNCA, and GBA — converge on the α-synuclein-lysosomal axis. LRRK2 regulates autophagy and immune signaling; SNCA encodes α-synuclein (the primary component of Lewy bodies); GBA loss-of-function impairs lysosomal degradation of α-synuclein.
Understanding your Parkinson's genetic status has transformed clinical implications: monogenic findings like LRRK2 variants qualify you for disease-modifying LRRK2 kinase inhibitor trials (DNL201, BIIB122) — among the most promising precision medicine advances in neurodegeneration. GBA variant findings enable eligibility for substrate reduction therapy trials. For all genetic findings, cascade testing of family members, enrollment in longitudinal biomarker studies, and presymptomatic screening become possible. Parkinson's genetics is rapidly transitioning from academic interest to clinical actionability with real treatment options.
Standard PD panels test limited genes. Over 25% of genetic PD risk comes from loci panels don't capture.
LRRK2-only testing misses GBA variants and polygenic risk
LRRK2-focused testing, commonly offered for Parkinson's disease, misses GBA variants, SNCA gene dosage changes, recessive PD genes (PARK2, PINK1, DJ-1), and the broader polygenic risk landscape. GBA testing is complicated by a highly homologous pseudogene (GBAP1) that can cause sequencing misalignment and false results. SNCA gene duplication and triplication require separate copy number analysis not always included in panels. Panels cannot capture the approximately 90 GWAS loci that collectively contribute to polygenic Parkinson's risk. Whole genome sequencing with proper depth and bioinformatic resolution captures all monogenic PD genes, GBA with pseudogene distinction, SNCA dosage, and genome-wide risk loci for comprehensive risk assessment.
Genetic findings now unlock disease-modifying trials and precision therapies
A LRRK2 gain-of-function variant qualifies you for LRRK2-targeted kinase inhibitor clinical trials (DNL201, BIIB122/denali) — potentially disease-modifying approaches that represent a genuine paradigm shift in neurodegeneration treatment. GBA loss-of-function findings enable eligibility for substrate reduction therapy trials and venglustat studies, with aggressive management of any Gaucher manifestations and awareness of faster motor and cognitive decline trajectories. SNCA variants qualify for gene-specific antisense oligonucleotide trials in development. For all genetic findings, enrollment in longitudinal biomarker studies (PPMI) enables presymptomatic progression tracking and trial readiness.
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.
