NLRP12-associated systemic autoinflammatory diseases in children

Area of Science:

• Immunology
• Genetics
• Pediatrics

Background:

• Systemic autoinflammatory diseases (SAIDs) involve innate immune dysregulation and excessive inflammation.
• NLRP12-related autoinflammatory disease (NLRP12-AID), also known as familial cold autoinflammatory syndrome 2 (FCAS2), is a rare, autosomal dominant disorder caused by NLRP12 gene mutations.
• This condition primarily affects children, presenting with periodic fevers and multisystem inflammatory damage.

Purpose of the Study:

• To summarize the clinical characteristics and pathogenesis of pediatric NLRP12-AID cases.
• To provide insights into the clinical diagnosis and treatment strategies for NLRP12-AID in children.
• To highlight the potential impact of emerging therapies on pediatric patient quality of life.

Main Methods:

• Review of reported pediatric cases of NLRP12-AID.
• Analysis of genetic mutations in the NLRP12 gene.
• Summary of clinical manifestations and diagnostic approaches.

Main Results:

• 33 pediatric NLRP12-AID cases and 21 distinct mutation types have been documented.
• Key symptoms include periodic fever and multisystem inflammation.
• Diagnosis relies on early clinical recognition and genetic testing.

Conclusions:

• NLRP12-AID is a distinct monogenic autoinflammatory disease affecting children.
• Genetic analysis of the NLRP12 gene is crucial for diagnosis.
• Targeted therapies, particularly those inhibiting interleukin-1 pathways, offer improved treatment prospects.
