Congenital Disorder Of Glycosylation, Type Iic; Cdg2c

Description

Congenital disorder of glycosylation type IIc (CDG2C) is an autosomal recessive disorder characterized by moderate to severe psychomotor retardation, mild dysmorphism, and impaired neutrophil motility. It is a member of a group of disorders with a defect in the processing of protein-bound glycans. For a general overview of congenital disorders of glycosylation (CDGs), see CDG1A (OMIM ) and CDG2A (OMIM ).The neutrophil defect in CDG2C has been referred to as 'leukocyte adhesion deficiency type II' (LAD2), which is a manifestation of the disorder; there are no cases of 'primary' LAD II (Frydman, 1996).Etzioni and Harlan (1999) provided a comprehensive review of both LAD1 (OMIM ) and LAD2. While the functional neutrophil studies are similar in the 2 LADs, the clinical course is milder in LAD2. Furthermore, patients with LAD2 present other abnormal features, such as growth and mental retardation, which are related to the primary defect in fucose metabolism. Delayed separation of the umbilical cord occurs in LAD1.
