Galactosemia is an inborn error of galactose metabolism secondary to deficiency of galactose-1-phosphate uridyl transferase (GALT). GALT is a polymorphic enzyme and Duarte (D) is the most common enzyme variant. This variant is characterized by faster electrophoretic mobility and reduced activity. Du

The enzyme galactose-1-phosphate uridyl transferase (E.C.2.7.7.12), which has an important function in the metabolism of galactose, exists in multiple molecular forms. The different phenotypes are genetically determined. They can be distinguished according to their electrophoretic mobility. The enzy
The frequency of variants of galactose-1-phosphate uridyl transferase was determined among the nine Greek populations by studying a sample of 1570 unselected individuals. Average frequency of normal allele GALT=0.942, galactosemia gen GALTG=0.0021 and the Duarte variant gene GALTD=0.0548 were observ
