COG5
Function
Required for normal Golgi function.
Involvement in disease
Congenital disorder of glycosylation 2I
CDG2I
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. Congenital disorder of glycosylation type 2I is characterized by mild neurological impairments.
None
The disease is caused by variants affecting the gene represented in this entry.
