Galactokinase Deficiency

Common Name(s)

Galactokinase Deficiency

Galactokinase deficiency, or galactosemia type 2, is a type of galactosemia that affects how the body processes a simple sugar called galactose.  A small amount of galactose is present in many foods. It is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas. The signs and symptoms of galactosemia result from an inability to use galactose to produce energy. Galactokinase deficiency causes fewer medical problems than the classic type. Affected infants usually develop cataracts, but otherwise experience few long-term complications. This condition is caused by mutations in the GALK1 gene and is inherited in an autosomal recessive fashion.

[Mutation P28T in gene GK1 as the cause of a familial galactokinase deficiency].
 

Author(s): M Girós, M D Bóveda, A Vázquez de la Cruz, P Lázaro, A Gata, A Solar Boga, P Briones

Journal: Arch Soc Esp Oftalmol. 2003 Feb;78(2):111-4.

 

To alert about galactokinase deficiency (GK) as a possible cause of infantile cataracts, and even presenile cataracts in heterozygous carriers. Diagnosis by enzyme and galactitol determination would lead to the introduction of a galactose-free diet which completely prevents the damage.

Galactokinase deficiency is an inborn error in the first step of galactose metabolism. Its major clinical manifestation is the development of cataracts in the first weeks of life. It has also been suggested that carriers of the deficiency are predisposed to presenile cataracts developing ...
