How to treat galactosemia in infants?
This is usually accomplished by switching the baby from drinking breast milk or a milk-based formula to drinking a low galactose formula, such as soy or elemental formula.
What is the mutation of Duarte galactosemia?
Duarte variant galactosemia, sometimes called just Duarte galactosemia or “DG,” is much more common than classic or clinical variant galactosemia in many populations and also results from mutations in the GALT gene. However, instead of carrying severe mutations in both copies of their GALT gene, patients with Duarte variant galactosemia carry one GALT copy with a severe (G) mutation and a second GALT copy that is only very mildly impaired and that shows characteristic sequence changes that classify it as "Duarte” (also called D or D2).
What is the genetic makeup of a galactose?
Patients with classic galactosemia are sometimes described as having the genetic makeup "G/G.". When a person who does not have galactosemia consumes food containing lactose (e.g., dairy products such as milk, cheese, butter), their body breaks down the lactose into galactose and glucose, and then further metabolizes both of these sugars.

Newborns with Duarte variant galactosemia may or may not be detected by the same newborn screening test that detects classic or clinical variant galactosemia. Specifically, some newborn screening protocols detect Duarte variant galactosemia, while others do not.
Can galactose build up in the body?
When a person with galactosemia consumes food containing lactose or galactose they are not able to fully metabolize the galactose, so it can build up in their cells and tissues. Galactose that is synthesized in the body may also build up.
