VEXAS syndrome: a diagnostic puzzle

Area of Science:

• Genetics and immunology
• Somatic mutations in autoinflammatory diseases

Background:

• VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is an adult-onset autoinflammatory condition.
• It results from acquired UBA1 gene deficiency in hematopoietic progenitor cells.
• The syndrome presents a wide range of phenotypes, including vasculitis, relapsing polychondritis, and Sweet's syndrome, often puzzling clinicians until its identification in late 2020.

Purpose of the Study:

• To describe the clinical features of VEXAS syndrome.
• To review diagnostic approaches for VEXAS syndrome.
• To discuss future research directions for somatic mutation-driven inflammatory diseases.

Main Methods:

• Literature review of VEXAS syndrome clinical features.
• Analysis of diagnostic strategies for VEXAS syndrome.
• Discussion of emerging research in somatic mutation-related inflammatory disorders.

Main Results:

• VEXAS syndrome exhibits a broad clinical spectrum, challenging early diagnosis.
• Diagnostic criteria and approaches have been refined since its identification.
• Understanding somatic mutations is crucial for advancing autoinflammatory disease research.

Conclusions:

• VEXAS syndrome is a significant, newly recognized autoinflammatory disorder.
• Accurate diagnosis relies on recognizing its diverse clinical manifestations and genetic basis.
• Further research into somatic mutations will likely uncover more disease mechanisms and therapeutic targets.
