Fifteen minute consultation: managing children with HNF1B pathogenic variants

Area of Science:

• Genetics and genomics
• Pediatric medicine
• Endocrinology

Background:

• Hepatocyte nuclear factor 1 beta (HNF1B) related disease presents with multisystemic manifestations.
• Renal developmental disorders and diabetes are the most common clinical features.
• Increased utilization of genomic testing leads to more frequent identification of pathogenic HNF1B variants in children.

Purpose of the Study:

• To provide a practical management guide for pediatricians.
• To outline long-term follow-up strategies for children with HNF1B related disease.
• To enhance clinical recognition and care for HNF1B variants.

Main Methods:

• Literature review focusing on HNF1B related disease in pediatric populations.
• Synthesis of current clinical guidelines and research findings.
• Expert consensus on management and follow-up protocols.

Main Results:

• HNF1B variants are associated with a wide spectrum of clinical features beyond renal and endocrine systems.
• Early diagnosis and multidisciplinary management are crucial for optimal outcomes.
• Long-term surveillance is necessary to monitor for disease progression and associated comorbidities.

Conclusions:

• Pediatricians require updated guidance for managing HNF1B related disease.
• A proactive approach to management and follow-up can improve the quality of life for affected children.
• Further research is needed to fully elucidate the genotype-phenotype correlations and therapeutic strategies.
