Carbohydrate deficient glycoprotein syndrome; multiple abnormalities and diagnostic delay.

Abstract

A 3 week old boy presented with abnormal thyroid function, and was treated with thyroxine. He developed multisystem disease including deafness and nephrotic syndrome, and died aged 3 months. Carbohydrate deficient glycoprotein syndrome (CDGS) was diagnosed post-mortem. CDGS should be considered in all infants with apparently unrelated multiple clinical or biochemical abnormalities.
