Medical Definition of GALT
GALT: The lack of the enzyme to break down the sugar (galactose-1-phosphate uridyl transferase) causes the genetic metabolic disease called galactosemia. Galactosemia is an elevated level of galactose in the blood. GALT is also the acronym for the gene that encodes the enzyme. Galactosemia causes liver dysfunction, susceptibility to infections, failure to thrive, ovarian problems, and cataracts.
