The Austrian Screening Program examined during 12 years 1,002.424 newborns and uncovered 23 cases of Galactosemia by Transferase deficiency, 6 by Kinase deficiency as well as 1 case of Phosphoglucomutase deficiency, 1 of porto-caval shunt and 1 congenital liver cirrhosis. Among the 23 Transferase deficiencies 18 took a fulminating course and 8 of these died. Since introduction of exchange transfusion as emergency treatment and acceleration of the screening procedure only 2 among 11 have died. Half of all Galactosemia cases, Transferase and Kinase, show already at the first examination (2. week) a cataract which however is reversible. In contrast to Kinase deficiency all cases of Transferase deficiency exhibit mental retardation if they grow older. Since treatment is early (9, 7 days), easy and the IQ already at 4 years 10 points below that of treated PKU's of same age a congenital brain damage has to be considered. Galactosemia by Transferase deficiency is in Western-Austria significantly more frequent than in Eastern-Austria. 17 boys compare with 6 girls. Among 6 cases of Galactosemia by Kinase deficiency 1 belonged to a Gippsy and 2 to Yugoslavian guest worker families. The 23 cases with Transferase deficiency had 45 siblings among whom 11 also were galactosemic. In 8 sibships the clinical course was of the same typ, but in 1 family one child showed the fulminating the other the subacute course.
