Classic galactosemia (GALT)


Classic galactosemia (GALT) is an inherited condition in which the body is unable to properly digest galactose. Galactose is a sugar found in all foods that contain milk. If a child with GALT eats galactose, undigested sugars build up in the blood rather than being used for energy. If GALT is left untreated, it can cause seizures, serious blood infections, liver damage, or even death. When the condition is identified early in life and proper treatment is begun immediately, children with GALT often can lead healthy lives.

This condition is also known as: GALT Deficiency, galactose-1-phosphate uridyltransferase deficiency, galactosemia.
