Summaries for Congenital Disorder of Glycosylation, Type Iio

UniProtKB/Swiss-Prot : 75 Congenital disorder of glycosylation 2O: A form of congenital disorder of glycosylation, a genetically heterogeneous group of autosomal recessive, multisystem disorders 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. CDG2O is characterized by hepatosplenomegaly, liver failure, hypotonia, and psychomotor disability.

MalaCards based summary : Congenital Disorder of Glycosylation, Type Iio, also known as cdg2o, is related to congenital disorder of glycosylation, type ii and congenital disorder of glycosylation, type iik. An important gene associated with Congenital Disorder of Glycosylation, Type Iio is CCDC115 (Coiled-Coil Domain Containing 115), and among its related pathways/superpathways are Tuberculosis and Phagosome. Affiliated tissues include liver, bone and skin, and related phenotypes are ptosis and seizures

Disease Ontology : 12 A congenital disorder of glycosylation type II that has material basis in an autosomal recessive mutation of CCDC115 on chromosome 2q21.1.

OMIM : 57 Congenital disorder of glycosylation type IIo (CDG2O) is an autosomal recessive metabolic disorder characterized by infantile onset of progressive liver failure, hypotonia, and delayed psychomotor development. Laboratory abnormalities include elevated liver enzymes, 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 a general discussion of CDGs, see CDG1A (212065). (616828)
