B4GALT1-Congenital Disorders of Glycosylation Presents as a Non-Neurologic Glycosylation Disorder with Hepatointestinal Involvement

The clinical phenotype of congenital disorders of glycosylation is heterogeneous, mostly including a severe neurological involvement and multisystem disease. We identified a novel patient with a galactosyltransferase deficiency with mild hepatopathy and coagulation anomalies, but normal psychomotor development. The tissue-specific expression of the defective B4GALT1 gene correlated with the clinical phenotype.
