[Genetic methods for analysis of autoinflammatory diseases]

Area of Science:

• Immunology
• Genetics
• Pediatrics

Background:

• The range of autoinflammatory diseases and their genetic underpinnings has grown significantly.
• Some monogenic autoinflammatory disorders present without prominent fever, alongside autoimmune issues and infection susceptibility.

Purpose of the Study:

• To emphasize the importance of identifying the genetic cause of autoinflammatory diseases.
• To guide the appropriate use of genetic testing in diagnosing autoinflammation.

Main Methods:

• Clinical presentation guides the choice of genetic testing.
• Targeted gene sequencing for suspected disorders.
• Next-generation sequencing (NGS) methods like panel sequencing, exome sequencing, and array comparative genomic hybridization (CGH) for undiagnosed cases.

Main Results:

• Autoinflammatory diseases involve dysregulated cytokine activity (IL-1β, TNF-α, type 1 IFNs).
• Specific genetic mutations lead to distinct autoinflammatory phenotypes.
• NGS offers comprehensive genetic analysis when clinical presentation is unclear.

Conclusions:

• Accurate genetic diagnosis is essential for effective, targeted treatment of autoinflammatory diseases.
• Genetic testing strategies should be tailored to individual patient presentations.
• Advances in NGS enable diagnosis even in complex or atypical cases.
