Current and future advances in genetic testing in systemic autoinflammatory diseases.

Area of Science:

• Immunology
• Genetics
• Rare Diseases

Background:

• Systemic autoinflammatory diseases (SAIDs) result from innate immune system dysregulation, causing heightened immune responses.
• Clinical diagnosis of SAIDs is challenging due to rarity, overlapping phenotypes, and genetic complexity.
• Environmental and epigenetic factors also influence SAID clinical presentation.

Purpose of the Study:

• To review recent advancements in genetic testing for diagnosing SAIDs.
• To discuss challenges encountered during the molecular diagnosis of SAIDs.
• To highlight the importance of molecular diagnosis for treatment, prognosis, and genetic counseling.

Main Methods:

• Review of current literature on genetic testing methodologies for SAIDs.
• Analysis of over 30 identified genes associated with monogenic SAIDs and their inheritance patterns.
• Discussion of emerging genetic testing technologies and databases.

Main Results:

• Over 30 genes are linked to monogenic SAIDs, with varied inheritance patterns and phenotypes.
• Somatic mutations are increasingly recognized in several SAID conditions.
• New genetic testing approaches are improving diagnostic capabilities.

Conclusions:

• Molecular diagnosis is essential for confirming SAIDs, guiding treatment, and informing prognosis.
• Understanding the genetic basis of SAIDs is critical for effective patient management and genetic counseling.
• Ongoing development in genetic testing promises to overcome diagnostic obstacles.
