Hereditary periodic fever syndromes

Area of Science:

• Genetics
• Immunology
• Molecular Medicine

Background:

• Hereditary periodic fever syndromes are autoinflammatory disorders characterized by recurrent, unprovoked inflammation.
• While the molecular basis for many of these conditions is increasingly understood, pathogenesis remains unclear for some.
• Recent genetic discoveries have paved the way for novel therapeutic strategies.

Purpose of the Study:

• To review the current understanding of hereditary periodic fever syndromes.
• To highlight the genetic basis and pathogenesis of specific disorders.
• To discuss emerging therapeutic approaches.

Main Methods:

• Literature review of genetic periodic fever syndromes.
• Analysis of molecular mechanisms underlying Familial Mediterranean Fever (FMF), Tumour Necrosis Factor Receptor-1-Associated Periodic Syndrome (TRAPS), Hyper IgD Periodic Fever Syndrome (HIDS), and Muckle-Wells Syndrome (MWS).
• Discussion of treatment outcomes and future prospects.

Main Results:

• Familial Mediterranean Fever (FMF) is linked to MEFV gene mutations, with severity correlating to specific mutations.
• Tumour Necrosis Factor Receptor-1-Associated Periodic Syndrome (TRAPS) results from TNFRSF1A mutations, leading to inflammation via unopposed TNF-alpha action; treatment with TNF-receptor analogues shows promise.
• Hyper IgD Periodic Fever Syndrome (HIDS) is caused by MVK gene mutations leading to mevalonate kinase deficiency; Muckle-Wells Syndrome (MWS) and familial cold urticaria (FCU) are likely allelic, with the gene identified but not yet isolated.

Conclusions:

• Genetic elucidation of periodic fever syndromes is advancing rapidly.
• Understanding the molecular basis is crucial for developing targeted therapies.
• Further research is needed to fully elucidate the pathogenesis of some syndromes and identify causative genes for others.
