Involvement in diseasei

Congenital disorder of glycosylation 1M (CDG1M) [MIM:610768]: 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. CDG1M is a very severe disease with death occurring in early life.
Note: The disease is caused by mutations affecting the gene represented in this entry.1 Publication
