Galactokinase is a major enzyme for the metabolism of galactose and its deficiency causes congenital cataracts during infancy and presenile cataracts in the adult population. [provided by RefSeq, Jul 2008]
GALK1 (Galactokinase 1) is a Protein Coding gene. Diseases associated with GALK1 include Galactosemia Ii and Galactosemia Iii. Among its related pathways are Galactose metabolism and Metabolism. Gene Ontology (GO) annotations related to this gene include galactose binding and galactokinase activity. An important paralog of this gene is GALK2.
