GARD: 19 Congenital disorders of glycosylation (CDG) are a group of inherited metabolic disorders that affect a process called glycosylation. Glycosylation is the complex process by which all human cells build long sugar chains that are attached to proteins, which are called glycoproteins. There are many steps involved in this process, and each step is triggered by a type of protein called an enzyme. Individuals with a CDG are missing one of the enzymes that is required for glycosylation. The type of CDG that a person has depends on which enzyme is missing. Currently, there are 19 identified types of CDG. CDG type IA is the most common form. The symptoms of CDG vary widely among affected individuals. Some people have severe developmental delay, failure to thrive, and multiple organ problems, while others have diarrhea, low blood sugar (hypoglycemia), liver problems, and normal developmental potential. MalaCards based summary: Congenital Disorder of Glycosylation, Type in, also known as congenital disorder of glycosylation, is related to congenital disorder of glycosylation, type im and congenital disorder of glycosylation, type iim, and has symptoms including ataxia, myoclonus and seizures. An important gene associated with Congenital Disorder of Glycosylation, Type in is RFT1 (RFT1 Homolog), and among its related pathways/superpathways are Metabolism of proteins and Disease. The drugs Sorbitol and Acetazolamide have been mentioned in the context of this disorder. Affiliated tissues include liver, eye and heart, and related phenotypes are seizure and hypotonia Orphanet 58 Congenital disorder of glycosylation: A fast growing group of inborn errors of metabolism characterized by defective activity of enzymes that participate in glycosylation (modification of proteins and other macromolecules by adding and processing of oligosaccharide side chains). This group is comprised of phenotypically diverse disorders affecting multiple systems including the central nervous system, muscle function, immunity, endocrine system, and coagulation. The numerous entities in this group are subdivided, based on the synthetic pathway affected, into disorder of protein N-glycosylation, disorder of protein O-glycosylation, disorder of multiple glycosylation, and disorder of glycosphingolipid and glycosylphosphatidylinositol anchor glycosylation. Rft1-cdg: RFT1-CDG is a form of congenital disorders of N-linked glycosylation characterized by poorly coordinated suck resulting in difficulty feeding and failure to thrive; myoclonic jerks with hypotonia and brisk reflexes progressing to a seizure disorder; roving eyes; developmental delay; poor to absent visual contact; and sensorineural hearing loss. Additional features that may be observed include coagulation factor abnormalities, inverted nipples and microcephaly. The disease is caused by mutations in the gene RFT1 (3p21.1). OMIM®: 57 Congenital disorders of glycosylation (CDGs) are a genetically heterogeneous group of autosomal recessive disorders caused by enzymatic defects in the synthesis and processing of asparagine (N)-linked glycans or oligosaccharides on glycoproteins. Type I CDGs comprise defects in the assembly of the dolichol lipid-linked oligosaccharide (LLO) chain and its transfer to the nascent protein. These disorders can be identified by a characteristic abnormal isoelectric focusing profile of plasma transferrin (Leroy, 2006). For a discussion of the classification of CDGs, see CDG1A (212065). (612015) (Updated 08-Dec-2022) UniProtKB/Swiss-Prot: 73 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. Disease Ontology 11 Congenital disorder of glycosylation in: A congenital disorder of glycosylation I that is characterized by poorly coordinated suck resulting in difficulty feeding and failure to thrive, myoclonic jerks with hypotonia and brisk reflexes progressing to a seizure disorder, roving eyes, developmental delay, poor to absent visual contact, and sensorineural hearing loss and has material basis in homozygous or compound heterozygous mutation in the RFT1 gene on chromosome 3p21. Congenital disorder of glycosylation: A carbohydrate metabolic disorder that involves deficient or defective glycosylation of a variety of tissue proteins and/or lipids.
