Über einen Fall von atypischer Galaktosämie

Abstract

The case of a male infant suffering from clinical manifest galactosemia in connexion with a disease of only about 70% in uridyltransferase activity is characterized as atypical galactosemia. As compared with the described "Indiana variant" of a galactosemic female infant showing an unstable uridyltransferase activity this case demonstrates an unchanged enzyme activity still after 72 hrs. The metabolic disease of this patient clearly demonstrated that the lack of a typical pronounced reduction of enzyme activity maybe not the leading criterion for excluding the clinical diagnosis of galactosemia. In the present case only the consistent galactose-free diet lead to the decisive improvement of the clinical picture. The investigation of the family revealed the typical pattern of an autosomal recessive mode of heredity.
