Background. Congenital Disorders of Glycosylation(CDG) are a group of disorders caused by defects in the biosynthesis of glycoprotiens and other glycoconjugates. Incidence is the 1:50.000-1:100.000 population. The golden standard for screening is the isoelectric focusing of transferrin(IEFT) Objective of the study. To performe the screening by IEFT on suspected patients for diagnose the CDG. Material and Methods. About 40 patients of various ages(2mo – 15y) under clinical suspicions for CDG at Institute of Mother and Child were examined by IEFT in colaborations with Radboudumc, Netherlands and U.S.A. The spectrum of clinical presentations of patients was multisystem damage, predominant neurological manifestations Results. Half of patients had an early presentation with hypotonia, hepatomegaly, elevated transaminases, mild hypoglycemia and various changes on cerebral MRI. Eleven children had dysmorphic features, seizures, failure to thrive and mental retardation. Other patients presented coagulations abnormality, cutis laxa, inverted nipples, stroke-like episodes, strabismus, nistagmus and ataxia. Serum samples analyzed by IEFTf: 37 normal, 2 questionable and 1 abnormal paterns. Two samples questionable were the patients with galactosemiaadfructosemia, which give the fals positive results.The last positive sample is performing aditionally for glycomics profiling. Conclusion. The CDG is a rare metabolic disease with multisystem impairement and variety of simptoms that determine miss diagnose. A important step în CDG diagnosis is to exclude secondary abnormality of glycosylation as fructosemia, galactosemia, sever liver disease and transferrin polimorphys. |
