Scientific reports·2026

Systemic sclerosis (SSc) is a complex autoimmune disease involving fibrosis and vascular issues. Genetic factors, including family history and specific gene associations, are significant contributors to SSc development.

Area of Science:

  • Rheumatology
  • Genetics
  • Immunology

Background:

  • Systemic sclerosis (SSc) is a multisystem connective tissue disease.
  • Key features include fibrosis and ischemic atrophy.
  • The etiology is likely multifactorial, with genetic predisposition playing a role.

Purpose of the Study:

  • To explore the genetic underpinnings of Systemic Sclerosis.
  • To review evidence supporting a genetic predisposition to SSc.
  • To highlight the role of genetic methodologies in understanding SSc.

Main Methods:

  • Review of familial SSc reports and positive family history as a risk factor.
  • Examination of disease-association studies across various gene categories (fibrosis, vascular function, autoimmunity).

  • Consideration of linkage studies in specific populations (e.g., Choctaw Indians).

    • Main Results:

    • A positive family history is the strongest identified risk factor for SSc.
    • Studies have investigated genes related to fibrosis, vascular function, and autoimmunity.
    • Genetic predisposition is supported by familial aggregation and association studies.

    Conclusions:

    • Genetic factors significantly contribute to the multifactorial etiology of Systemic Sclerosis.
    • Advances in genetic methodologies are expected to enhance understanding of SSc.
    • Further research into the genetic basis of SSc is crucial for unraveling its complex pathogenesis.
