Background: NGLY1 encodes the enzyme N-glycanase that catalyzes protein deglycosylation in the process of protein degradation. Loss of function mutations in NGLY1 lead to a disorder of N-linked deglycosylation which is a rare multisystemic disease. The typical phenotype includes intellectual disability, liver dysfunction, muscular hypotonia, involuntary movements and decreased or absent tear production. Adrenal insufficiency has been previously reported in onl...

Background: Phosphoglucomutase 1 (PGM-1) deficiency is a congenital disorder of glycosylation caused by an impairment of glucose-1-phosphate and glucose-6-phosphate interconversion.The clinical phenotype of PGM1 deficiency is variable and includes several endocrine manifestations such as recurrent hypoglycemia and short stature, which may be associated with the decreased levels of growth hormone (GH), insulin like growth factor-1 (IGF1) ...
