Congenital disorder of glycosylation 2M
A disorder characterized by developmental delay, hypotonia, ocular anomalies, and brain malformations. Othere more variable clinical features included seizures, hypsarrhythmia, poor feeding, microcephaly, recurrent infections, dysmorphic features, shortened limbs, and coagulation defects. Congenital disorders of glycosylation are caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins and a wide variety of clinical features. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions.
