Summaries for Congenital Disorder of Glycosylation, Type Iig

UniProtKB/Swiss-Prot : 76 Congenital disorder of glycosylation 2G: 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. Clinical features of CDG2G include failure to thrive, generalized hypotonia, growth retardation and mild psychomotor retardation. CDG2G is biochemically characterized by a defect in O-glycosylation as well as N-glycosylation.

MalaCards based summary : Congenital Disorder of Glycosylation, Type Iig, also known as cdg2g, is related to cerebrocostomandibular syndrome. An important gene associated with Congenital Disorder of Glycosylation, Type Iig is COG1 (Component Of Oligomeric Golgi Complex 1). Affiliated tissues include bone, and related phenotypes are osteopenia and muscular hypotonia

Disease Ontology : 12 A congenital disorder of glycosylation type II that has material basis in a mutation of COG1 on chromosome 17q25.1.
