Summaries for Galactokinase Deficiency with Cataracts

NIH Rare Diseases : 50 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. last updated: 6/9/2011

MalaCards based summary : Galactokinase Deficiency with Cataracts, also known as galactokinase deficiency, is related to galactose epimerase deficiency and galactosemia, and has symptoms including cataract, impairment of galactose metabolism and increased intracranial pressure. An important gene associated with Galactokinase Deficiency with Cataracts is GALK1 (Galactokinase 1), and among its related pathways/superpathways are Metabolism and Glycosaminoglycan metabolism. The drugs Emtricitabine and Tenofovir have been mentioned in the context of this disorder. Affiliated tissues include eye, and related phenotype is Increased shRNA abundance (Z-score > 2).

Disease Ontology : 12 A galactosemia that involves an accumulation of galactose and galactitol secondary to the decreased conversion of galactose to galactose-1-phosphate by galactokinase.

OMIM : 54 Galactokinase deficiency is an autosomal recessive disorder that causes cataract formation in children not maintained... (230200) more...

UniProtKB/Swiss-Prot : 66 Galactosemia II: Autosomal recessive deficiency characterized by congenital cataracts during infancy and presenile cataracts in the adult population. The cataracts are secondary to accumulation of galactitol in the lenses.
