Resumo(s)
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. Distinct mutations on the L2HGDH gene have
been associated with the clinical and biochemical phenotype. Here we present three novel mutations (Gln197X, Gly211Val
and c.540+1 G4A), which increase the present deleterious collection of L2HGDH gene up to 35 mutations that we have
compiled in this study. In addition, we used the haplotypic information based on polymorphic markers to demonstrate the
common origin of Gly57Arg harboring chromosomes.
