Summaries for D-2-Hydroxyglutaric Aciduria 1

NIH Rare Diseases : 53 D-2-alpha hydroxyglutaric aciduria is an inheritedmetabolic condition that is associated with progressive brain damage. Signs and symptoms of this condition include developmental delay, seizures, hypotonia, and abnormalities in the largest part of the brain (the cerebrum), which controls many important functions such as muscle movement, speech, vision, thinking, emotion, and memory. D-2-alpha hydroxyglutaric aciduria is caused by changes (mutations) in the D2HGDH gene and is inherited in an autosomal recessive manner. Treatment is focused on alleviating the signs and symptoms of the condition, such as medications to control seizures.

MalaCards based summary : D-2-Hydroxyglutaric Aciduria 1, also known as d-2-hydroxyglutaric aciduria, is related to 2-hydroxyglutaric aciduria and l-2-hydroxyglutaric aciduria, and has symptoms including seizures, muscle weakness and dyspnea. An important gene associated with D-2-Hydroxyglutaric Aciduria 1 is D2HGDH (D-2-Hydroxyglutarate Dehydrogenase), and among its related pathways/superpathways are Citrate cycle (TCA cycle) and Glutathione metabolism. Affiliated tissues include brain, eye and skeletal muscle, and related phenotypes are macrocephaly and frontal bossing

Disease Ontology : 12 An 2-hydroxyglutaric aciduria that involves developmental delay, seizures, weak muscle tone (hypotonia), and abnormalities in the largest part of the brain (the cerebrum), which controls many important functions such as muscle movement, speech, vision, thinking, emotion, and memory.

OMIM : 57 D-2-hydroxyglutaric aciduria is a neurometabolic disorder first described by Chalmers et al. (1980). Clinical symptoms include developmental delay, epilepsy, hypotonia, and dysmorphic features. Mild and severe phenotypes were characterized (van der Knaap et al., 1999). The severe phenotype is homogeneous and is characterized by early infantile-onset epileptic encephalopathy and, often, cardiomyopathy. The mild phenotype has a more variable clinical presentation. (600721)

UniProtKB/Swiss-Prot : 75 D-2-hydroxyglutaric aciduria 1: A rare recessive neurometabolic disorder causing developmental delay, epilepsy, hypotonia, and dysmorphic features. Both a mild and a severe phenotype exist. The severe phenotype is homogeneous and is characterized by early infantile-onset epileptic encephalopathy and cardiomyopathy. The mild phenotype has a more variable clinical presentation. Diagnosis is based on the presence of an excess of D-2- hydroxyglutaric acid in the urine.
