Disease Associations Congenital disorder of glycosylation 1O (CDG1O) [MIM:612937]: 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. CDG1O patients have increased serum creatine kinase, dystrophic changes on muscle biopsy, and reduced O-mannosylation of alpha-dystroglycan. {ECO:0000269PubMed:19576565}. Note=The disease is caused by mutations affecting the gene represented in this entry.
