Core Tip
Core Tip: Glycogen storage diseases (GSDs) are a group of clinically and genetically heterogeneous diseases. The various subtypes of hepatic GSDs are often clinically overlapping, especially in hepatic GSDs. Early diagnosis and proper dietary therapy are paramount for optimal clinical outcomes. Certain clinical features and laboratory derangements such as hypoglycemia, elevated liver enzymes and abnormal lipid profile are helpful in diagnosis. Liver biopsy is an invasive diagnostic test, which has recently been replaced by genetic testing. Next-generation sequencing is now being used more frequently for definitive diagnosis of GSD.
