[Periodic fever syndromes]

Area of Science:

• Immunology
• Genetics
• Rheumatology

Background:

• Periodic fever syndromes (PFS) are a group of autoinflammatory disorders characterized by recurrent, unprovoked inflammatory episodes.
• Recent years have seen the identification of genetic underpinnings for several hereditary forms of PFS.

Purpose of the Study:

• To review the progress in understanding the genetic basis of hereditary periodic fever syndromes.
• To explore the functional defects associated with identified genes and their role in inflammatory pathways.
• To highlight the implications for future therapeutic strategies and patient prognosis.

Main Methods:

• Literature review focusing on genetic discoveries in PFS.
• Analysis of the functional consequences of identified gene mutations.
• Examination of the links between genetic defects, apoptotic proteins, and signal transduction pathways.

Main Results:

• Five hereditary autoinflammatory syndromes with identified genetic causes are discussed: Familial Mediterranean Fever, Cryopyrinopathies (including CINCA), TNF-receptor associated periodic syndrome, Cyclic Neutropenia, and PFAPA syndrome.
• The progression from clinical description to genetic identification and functional defect analysis has been significant.
• Understanding these molecular pathways is crucial for developing targeted therapies.

Conclusions:

• The genetic and molecular understanding of periodic fever syndromes has advanced significantly.
• This knowledge facilitates the development of more specific and effective treatment options.
• Future research focusing on these pathways promises improved prognosis and outcomes for patients with PFS.
