Autoimmune connective tissue disease with heritability ~55%. HLA class II and interferon pathway genes are major risk factors.
How Genetic Is Systemic Sclerosis (Scleroderma)?
Systemic Sclerosis (Scleroderma) involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 55%, though no single gene determines outcome on its own.
Key genes associated with Systemic Sclerosis (Scleroderma): HLA-DPB1 IRF5 STAT4. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Systemic Sclerosis (Scleroderma)?
Family history can be informative for Systemic Sclerosis (Scleroderma), but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
Frequently Asked Questions
Is Systemic Sclerosis (Scleroderma) genetic?
Multiple genes and environmental factors interact to influence risk. Studies suggest heritability of approximately 55%. Key genes involved include HLA-DPB1 IRF5 STAT4.
Can a DNA test reveal my risk of Systemic Sclerosis (Scleroderma)?
Genetic testing can identify relevant variants, though Systemic Sclerosis (Scleroderma) risk is influenced by many factors. Talk to your doctor about appropriate testing.
Does family history matter for Systemic Sclerosis (Scleroderma)?
Family history can be informative for Systemic Sclerosis (Scleroderma), but its predictive power is limited because many genes with small individual effects combine with environmental influences.
Is Systemic Sclerosis (Scleroderma) hereditary, meaning it's passed directly from parent to child?
Systemic Sclerosis (Scleroderma) follows a polygenic inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
