Transferrin mutations at the glycosylation site complicate diagnosis of congenital disorders of glycosylation type I

Popis výsledku v původním jazyce

Congenital Disorders of Glycosylation (CDG) form a group of metabolic disorders caused by deficient glycosylation of proteins and/or lipids. Isoelectric focusing (IEF) of serum transferrin is the most common screening method to detect abnormalities of protein N-glycosylation. On basis of the isofocusing profile, patients can be grouped in CDG type I or CDG type II. Secondary causes, such as the presence of a transferrin protein polymorphism can complicate interpretation and must be excluded before time-consuming diagnostics is initiated. Several protein variants of transferrin are known that result in a shift in pI and thereby result in double bands in IEF. Incubation of the plasma sample with neuraminidase can indicate the presence of a protein polymorphism by showing double bands at the position of asialotransferrin. Here, we present two cases with a novel protein polymorphism, resulting in a single transferrin isoform after neuraminidase digestion. Mass spectrometric analysis of imm
