L-2-hydroxyglutaric aciduria (L2HGA), which is a rare autosomal recessive metabolic disorder caused by mutations in the encoding L2HGDH gene. Neurological symptoms are the main predominant clinical signs. The distinctive feature is the specific multifocal lesion of the white matter detected on magnetic resonance imaging (MRI). A 7-year-old male patient of Turkish origin was admitted to the hospital because of hand tremors. Physical examination revealed macrocephaly, intention tremors, walking disability and ataxic gait. Urine organic acid analysis showed increased excretion of L-2-hydroxyglutaric acid (L2HG acid). Analysis of the L2HGDH gene revealed a novel homozygous c.368A>G, p. (Tyr123Cys) mutation. L-2-hydroxyglutaric aciduria is a cerebral organic aciduria that may lead to various neurological complications. Early recognition of symptoms of L2HGA is important for initiation of supportive therapy that may slow down the progression of the disease. |
