Summaries for Congenital Disorder of Glycosylation, Type Ik

OMIM : 57 Congenital disorders of glycosylation (CDGs) comprise a group of multisystem diseases with mostly severe psychomotor and mental retardation. Type I CDG comprises those disorders in which there are defects that affect biosynthesis of dolichol-linked oligosaccharides in the cytosol or the endoplasmic reticulum (ER), as well as defects involving the transfer of oligosaccharides onto nascent glycoproteins. Type II CDG comprises all defects of further trimming and elongation of N-linked oligosaccharides in the ER and Golgi (Schwarz et al., 2004). CDG1K is a type I CDG characterized by predominant neurologic involvement. Survival ranges from the second day of life to adulthood. The liver is affected in a minority of patients and shows hepatomegaly, edema, ascites, cholestatic jaundice, portal hypertension, and Budd-Chiari syndrome (summary by Marques-da-Silva et al., 2017). For a general discussion of CDGs, see CDG1A (212065). (608540)

MalaCards based summary : Congenital Disorder of Glycosylation, Type Ik, also known as cdg1k, is related to alg1-congenital disorder of glycosylation and congenital disorder of glycosylation, type in. An important gene associated with Congenital Disorder of Glycosylation, Type Ik is ALG1 (ALG1, Chitobiosyldiphosphodolichol Beta-Mannosyltransferase). Affiliated tissues include liver, and related phenotypes are seizures and global developmental delay

UniProtKB/Swiss-Prot : 75 Congenital disorder of glycosylation 1K: A form of congenital disorder of glycosylation, a multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions.
