Scleroderma Genetic Testing — HLA, IRF5 & Systemic Sclerosis | Dante Labs
SCLERODERMA — GENETIC RISK

Scleroderma Genetic Susceptibility — HLA genotype and immune regulatory gene variants influence systemic sclerosis risk, disease subtype, and autoantibody profile, enabling earlier diagnosis and organ-specific surveillance.

Whole genome sequencing evaluates HLA haplotypes, interferon pathway genes (IRF5, STAT4), and fibrosis-related variants — providing the genetic architecture underlying scleroderma susceptibility and clinical phenotype.

ABOUT SCLERODERMA — GENETIC RISK

Scleroderma — Genetic Susceptibility

Systemic sclerosis (scleroderma, SSc) is an autoimmune connective tissue disease characterized by vascular dysfunction, immune activation, and progressive fibrosis. It affects approximately 100,000 Americans. SSc has significant genetic heritability — first-degree relatives have 13-15x increased risk. HLA class II variants (DRB1*11:04, DPB1*13:01) are the strongest genetic associations, and different HLA alleles associate with specific autoantibody subtypes.

Non-HLA genetic associations include IRF5 (interferon regulatory factor 5 — also associated with lupus), STAT4, CD247, TNFSF4, and BANK1. These innate and adaptive immune pathway genes support the autoimmune pathogenesis model. Genetic variants in fibrosis pathways (CTGF, FBN1 microsatellite) may influence disease severity and organ involvement.

Clinical genetic utility: HLA genotyping can support SSc subtype classification (limited vs. diffuse), autoantibody prediction, and organ involvement risk stratification. Anti-RNA polymerase III autoantibodies (associated with specific HLA genotypes) require cancer screening (concurrent malignancy in ~10%). Nintedanib (anti-fibrotic) is FDA-approved for SSc-ILD, and tocilizumab for early diffuse SSc — treatment selection increasingly informed by molecular disease characterization.

Anti-RNA polymerase III scleroderma has ~10% concurrent cancer rate. Cancer screening is REQUIRED for this autoantibody subtype. HLA genotype predicts which autoantibody pattern — and therefore which cancer screening — applies.

WHY WHOLE GENOME SEQUENCING

Scleroderma subtype, autoantibody profile, and cancer risk correlate with HLA genotype. WGS provides the genetic architecture that supports precision management of this heterogeneous disease.

HLA genotype predicts scleroderma autoantibody subtype — which determines organ surveillance and cancer screening

Different HLA alleles associate with anti-centromere (limited SSc, pulmonary hypertension risk), anti-topoisomerase (diffuse SSc, ILD risk), and anti-RNA polymerase III (diffuse SSc, cancer screening required). WGS-derived HLA typing supports subtype classification and organ-specific surveillance planning.

Nintedanib and tocilizumab are now available for SSc — appropriate subtype classification guides treatment selection

Nintedanib (anti-fibrotic) is approved for SSc-ILD. Tocilizumab for early diffuse SSc. These targeted therapies require accurate disease subtyping for appropriate use. Genetic-autoantibody correlation supports the classification that drives treatment selection.

WHAT SEQUENCING YOUR ENTIRE GENOME ACTUALLY MEANS
01

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.

02

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.

03

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.

OUTCOMES

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.

WHO WE HELP

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.

ALREADY TESTED

You already took a DNA test. Here's what it couldn't tell you.

Most consumer DNA tests read less than 0.1% of your genome. We read all of it.

FREQUENTLY ASKED QUESTIONS

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.
