Summaries for Congenital Disorder of Glycosylation, Type if

UniProtKB/Swiss-Prot : 75 Congenital disorder of glycosylation 1F: 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.

MalaCards based summary : Congenital Disorder of Glycosylation, Type if, also known as congenital disorder of glycosylation type 1f, is related to ichthyosis and congenital disorder of glycosylation, type in, and has symptoms including seizures, ataxia and dry skin. An important gene associated with Congenital Disorder of Glycosylation, Type if is MPDU1 (Mannose-P-Dolichol Utilization Defect 1). Affiliated tissues include skin, eye and liver, and related phenotypes are seizures and muscular hypotonia

OMIM : 57 Congenital disorders of glycosylation (CDGs) are metabolic deficiencies in glycoprotein biosynthesis that usually cause severe mental and psychomotor retardation. Different forms of CDGs can be recognized by altered isoelectric focusing (IEF) patterns of serum transferrin. For a general discussion of CDGs, see CDG Ia (212065) and CDG Ib (602579). (609180)
