Genes and Microbiota Interaction in Monogenic Autoimmune Disorders

Area of Science:

• Immunology
• Genetics
• Microbiology

Background:

• Monogenic autoimmune disorders offer insights into immune tolerance mechanisms.
• Complex genetic and environmental factors disrupt immune homeostasis in these diseases.
• Current management focuses on symptoms due to limited research on rare diseases.

Purpose of the Study:

• To review the genetic characteristics of organ-specific and systemic monogenic autoimmune diseases.
• To summarize current literature on microbiota alterations in patients with these disorders.
• To explore the potential of microbiota modulation as a therapeutic strategy.

Main Methods:

• Literature review of genetic features of monogenic autoimmune diseases.
• Analysis of studies investigating microbiota composition in affected patients.
• Synthesis of findings on the interplay between genetics, microbiota, and autoimmunity.

Main Results:

• Genetic analysis has improved diagnosis but not disease management.
• Emerging evidence links microbiota dysbiosis to autoimmune disease onset.
• Specific genetic defects and associated microbiota profiles are identified.

Conclusions:

• Understanding genetic underpinnings is crucial for immune tolerance research.
• Microbiota composition represents a promising, novel target for therapeutic interventions.
• Further research is needed to elucidate the causal role of microbiota in monogenic autoimmunity.
