Test ID: CDGN
Congenital Disorders of N-Glycosylation, Serum
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Screening for N-linked congenital disorders of glycosylation
Providing information on specific structural oligosaccharide abnormalities to potentially direct further genetic testing
Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request
Congenital disorders of glycosylation (CDG) comprise a large group of inborn errors of metabolism affecting predominantly N- and O-glycosylation of proteins.
N-linked CDG commonly present as clinical syndromes with multisystemic involvement and a broad clinical spectrum.
In addition to transferrin and apolipoprotein CIII isoform analysis, this test also detects and analyzes N-linked oligosaccharides by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) for a more comprehensive evaluation of CDG.
Additional Tests Lists tests that are always performed, at an additional charge, with the initial tests.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| CDG | CDG, S | Yes | Yes |
Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
When this test is ordered, carbohydrate deficient transferrin for congenital disorders will always be performed at an additional charge.
