Classic galactosemia occurs when an enzyme called galactose-1-phosphate uridyltransferase (GALT) is missing or not functional. This liver enzyme is responsible for breaking down galactose (a sugar byproduct of lactose found in breast milk, cowâs milk and other dairy foods) into glucose.
Most commonly, galactosemia is caused by a mutation in the GALT gene. The GALT gene normally provides instructions for making an enzyme that functions in liver cells to break down the sugar galactose.f both parents are carriers, there is a 25% chance their child will have galactosemia. There are three different types of galactosemia. Each one is caused by a mutation in a different gene. Classic galactosemia is the most common form of this disorder, and the most severe.
