| 618885 | OMIM | Congenital disorder of glycosylation 2T (CDG2T) | A form of congenital disorder of glycosylation, a genetically heterogeneous group of 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. CDG2T is an autosomal recessive form characterized by global developmental delay, intellectual disability with language deficit, autistic features, behavioral abnormalities, epilepsy, chronic insomnia, white matter changes on brain imaging, dysmorphic features, decreased stature, and decreased high density lipoprotein cholesterol levels. The disease is caused by variants affecting the gene represented in this entry. |
