Clinical Report: Uncommon Hepatobiliary Complications in GLUT1 Deficiency Syndrome
Overview
This report details a case of GLUT1 deficiency syndrome (GLUT1DS) in a boy presenting with intractable seizures and hepatobiliary complications. The findings highlight the association between erythrocyte membrane instability and recurrent hemolysis, expanding the clinical spectrum of GLUT1DS.
Background
GLUT1 deficiency syndrome is a rare neurometabolic disorder primarily characterized by neurological symptoms. However, atypical manifestations, including hematologic and hepatobiliary complications, are increasingly recognized but remain poorly understood. Understanding these complications is crucial for comprehensive patient management and surveillance.
Data Highlights
Case presentation of a 5.5-year-old boy with GLUT1DS, including genetic findings and clinical symptoms.
Key Findings
The patient was diagnosed with GLUT1DS due to a heterozygous deletion in SLC2A1.
He exhibited persistent indirect hyperbilirubinemia and recurrent jaundice.
Chronic hemolysis was identified as a cause of anemia and abdominal pain.
Specialized tests revealed erythrocyte membrane instability linked to GLUT1 dysfunction.
This case underscores the need for multidisciplinary care beyond neurological symptoms.
Clinical Implications
Healthcare providers should be aware of the potential for atypical systemic manifestations in GLUT1DS, including hepatobiliary complications. Regular monitoring of erythrocyte membrane integrity may aid in early recognition and management of these complications.
Conclusion
This case emphasizes the importance of recognizing and addressing the broader clinical implications of GLUT1DS, particularly concerning hematologic and hepatobiliary health.
