Genetics, Epigenetics, and Genomics of Systemic Sclerosis

Area of Science:

• Immunology
• Genetics
• Autoimmune Diseases

Background:

• Systemic sclerosis (SSc) is a complex autoimmune disorder.
• Genetic predisposition plays a significant role in SSc development.
• Previous studies indicate multiple genetic loci are associated with SSc susceptibility.

Purpose of the Study:

• To review current knowledge on the genetics of Systemic Sclerosis (SSc).
• To explore observational evidence, genetic study modalities, and identified genes.
• To discuss gene expression variation, epigenetic mechanisms, and microRNA in SSc.

Main Methods:

• Literature review of observational evidence and genetic studies in SSc.
• Analysis of genetic loci and relevant genes implicated in SSc.
• Exploration of gene expression regulation, epigenetics, and microRNA functions.

Main Results:

• Multiple genetic loci contribute to SSc susceptibility.
• Gene expression variations and epigenetic factors, including microRNA, are crucial in SSc pathogenesis.
• Specific genes associated with SSc have been identified through various genetic studies.

Conclusions:

• Understanding the genetic architecture of SSc is vital for comprehending disease mechanisms.
• Epigenetic modifications, particularly microRNA, represent a promising area for SSc research.
• Further genetic and epigenetic investigations are needed to elucidate SSc etiology and identify therapeutic targets.
