Congenital Disorder of Glycosylation A Case Presentation

Congenital disorders of glycosylation (CDG) are a group of rare genetically inherited disorders that involve the malfunction of attaching sugar molecules to lipids, proteins, or other organic molecules through an enzymatic process. The resulting defect in glycoprotein and glycolipid synthesis often has a heterogeneous range of multisystemic effects ranging from mild dysmorphism to profound organ failure and subsequent death. There are 2 types of CDG, type I and type II, with multiple subtypes within each. This column is a case presentation about an infant who presented with CDG type Ik.
