Congenital disorders of glycosylation (CDG) comprise a diverse group of genetic diseases characterized by aberrant glycosylation that leads to severe multi-systematic effects. Despite advancements in understanding the underlying molecular mechanisms, curative options remain limited. This study employed computational methods to identify key molecular biomarkers for CDG-I and examine the pharmacological effects of Ginkgolide A (GA), a potent bioactive natural compound. We analyzed the GSE8440 microarray dataset to discover differentially expressed genes (DEGs) in patients compared to healthy individuals with CDG-I utilizing GEO2R.
