The purpose of the present work was to progress in our understanding of the pathophysiology of L-2-hydroxyglutaric aciduria, due to a defect in L-2-hydroxyglutarate dehydrogenase, by creating and studying a mouse model of this disease.
Founder effect confirmation of c.241A>G mutation in the L2HGDH gene and characterization of oxidative stress parameters in six Tunisian families with L-2-hydroxyglutaric aciduria.
Here, we report a pathogenic nonsense mutation in the L-2-HGDH gene found for the first time in an Italian patient affected by L-2-HGA, reinforcing the previously described phenotype of this rare metabolic disease and confirming the data indicating that mutations in the L-2-HGDH gene cause L-2-HGA.
L-2-hydroxyglutaric aciduria (L-2-HGA, MIM 236792) is a neurometabolic disorder caused by the toxic accumulation of high concentration of L-2-hydroxyglutaric acid in plasma and cerebrospinal fluid.
We describe late diagnosis of an adult with L-2-hydroxyglutaric aciduria (MIM 236792) on the basis of characteristic metabolite data and mutation analysis in the L2HGDH gene.
L-2-Hydroxyglutaric aciduria (L-2-HGA, MIM 236792) is a rare autosomal recessive neurodegenerative disorder characterized by psychomotor delay, cerebellar and extrapyramidal signs and subcortical leukoencephalopathy with basal ganglia and dentate nuclei involvement.
L-2-hydroxyglutaric aciduria: clinical and molecular study in three Tunisian families. Identification of a new mutation and inter-familial phenotype variability.
L-2-Hydroxyglutaric aciduria (L-2-OHGA) is a rare autosomal recessive neurometabolic disease linked to chromosome 14q21.1 and is caused by mutations in the gene that most likely encodes L: -2-hydroxyglutarate dehydrogenase, which normally catalyses L: -2-hydroxyglutarate to alpha-ketoglutarate.
We analyzed the L-2-HGA gene (L2HGDH), recently found to be mutated in consanguineous families with L-2-HGA, and identified seven novel mutations in 15 families.
We analyzed the L-2-HGA gene (L2HGDH), recently found to be mutated in consanguineous families with L-2-HGA, and identified seven novel mutations in 15 families.
It is concluded that L-2-hydroxyglutarate is normally metabolized to alpha-ketoglutarate in mammalian tissues and that L-2-hydroxyglutaric aciduria is caused by mutations in the gene that most likely encodes L-2-hydroxyglutarate dehydrogenase.
