Galactose-1-phosphate uridyltransferase (GALT) deficiency is the most common cause of galactosemia and requires lifelong restriction of dietary galactose.


Plasma galactose can be elevated in patients with galactosemia caused by GALT deficiency, galactokinase deficiency, or galactose mutarotase deficiency.


Classic galactosemia can be diagnosed by analysis of GALT enzyme.
