Whole exome sequencing reveals several novel variants in congenital disorders of glycosylation and glycogen storage diseases in seven patients from Iran

Congenital disorder of glycosylation (CDG) and Glycogen storage diseases (GSDs) are inborn metabolic disorders caused by defects in some metabolic pathways. These disorders are a heterogeneous group of diseases caused by impaired O‐ as well as N‐glycosylation pathways. CDG patients show a broad spectrum of clinical presentations; many GSD types (PGM1‐CDG) have muscle involvement and hypoglycemia.
