Screening for congenital disorders of glycosylation

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request



This testing is used to screen patients for suspected congenital disorders of glycosylation (N- and O-glycosylation defects as well as glycan structure analysis).


Congenital disorders of glycosylation (CDG) encompass over 100 genetic conditions spanning a broad clinical spectrum.


The main CDG profiles that can be identified by this analysis are type I, some type II, and mixed type CDG's.
