Summaries for Congenital Disorder of Glycosylation, Type Im

UniProtKB/Swiss-Prot : 75 Congenital disorder of glycosylation 1M: 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. CDG1M is a very severe disease with death occurring in early life.

MalaCards based summary : Congenital Disorder of Glycosylation, Type Im, also known as congenital disorder of glycosylation type 1m, is related to dolk-congenital disorder of glycosylation and dilated cardiomyopathy. An important gene associated with Congenital Disorder of Glycosylation, Type Im is DOLK (Dolichol Kinase). Affiliated tissues include skin, liver and bone, and related phenotypes are splenomegaly and hepatomegaly
