Monogenic Lupus: A Developing Paradigm of Disease

Area of Science:

• Immunology
• Genetics
• Rheumatology

Background:

• Monogenic lupus is a rare systemic lupus erythematosus (SLE) variant linked to single gene defects.
• It typically manifests as early-onset, severe disease, particularly affecting renal and central nervous systems.
• Numerous genes are now implicated, offering insights into complex autoimmune disease mechanisms.

Purpose of the Study:

• To review genes associated with monogenic lupus and lupus-like diseases.
• To elucidate pathogenic mechanisms driven by mutations in these genes.
• To enhance understanding of autoimmunity induction in monogenic lupus.

Main Methods:

• Literature review of genetic studies in monogenic lupus.
• Analysis of pathogenic mechanisms linked to identified gene mutations.
• Synthesis of current knowledge on gene-disease associations.

Main Results:

• A significant number of genes have been identified in monogenic lupus.
• Mutations in these genes disrupt key pathways involved in immune regulation.
• These disruptions contribute to the development of autoimmunity.

Conclusions:

• Monogenic lupus provides a simplified model to study SLE pathogenesis.
• Understanding these genetic defects is crucial for developing targeted therapies.
• Further research into these genes will illuminate broader autoimmune disease mechanisms.
