Immunodeficiency-47 (IMD47) is an X-linked recessive complex syndrome characterized by liver dysfunction, recurrent bacterial infections, hypogammaglobulinemia, and defective glycosylation of serum proteins. Some patients also have neurologic abnormalities (summary by Jansen et al., 2016). [from OMIM]

Congenital disorder of glycosylation type IIp (CDG2P) is an autosomal recessive metabolic disorder characterized by mild liver dysfunction, which may be found incidentally during adolescence. Laboratory abnormalities include elevated liver enzymes and alkaline phosphatase, coagulation factor deficiencies, hypercholesterolemia, and low ceruloplasmin. Serum isoelectric focusing of proteins shows a combined defect of N- and O-glycosylation, suggestive of a Golgi defect (summary by Jansen et al., 2016). For an overview of congenital disorders of glycosylation, see CDG1A (212065) and CDG2A (212066). [from OMIM]

Congenital disorder of glycosylation type IIw (CDG2W) is an autosomal dominant metabolic disorder characterized by liver dysfunction, coagulation deficiencies, and profound abnormalities in N-glycosylation of serum specific proteins. All reported patients carry the same mutation (602671.0017) (summary by Ng et al., 2021). For an overview of congenital disorders of glycosylation, see CDG1A (212065) and CDG2A (212066). [from OMIM]

Congenital disorder of glycosylation type 2v (CDG2V) is an autosomal recessive disorder characterized by neurodevelopmental delay and variable facial dysmorphisms (Polla et al., 2021). [from OMIM]

An anomaly of protein N-linked glycosylation, i.e., an abnormality of the protein glycosylation process in which a carbohydrate or carbohydrate derivative unit is added to a protein via a nitrogen atom in an amino acid residue in a protein. [from HPO]
