Summaries for Hypermethioninemia Due to Adenosine Kinase Deficiency

OMIM : 57 Hypermethioninemia due to adenosine kinase deficiency is an autosomal recessive inborn error of metabolism characterized by global developmental delay, early-onset seizures, mild dysmorphic features, and characteristic biochemical anomalies, including persistent hypermethioninemia with increased levels of S-adenosylmethionine (AdoMet) and S-adenosylhomocysteine (AdoHcy); homocysteine is typically normal (summary by Bjursell et al., 2011). (614300)

MalaCards based summary : Hypermethioninemia Due to Adenosine Kinase Deficiency, is also known as hypermethioninemia encephalopathy due to adenosine kinase deficiency. An important gene associated with Hypermethioninemia Due to Adenosine Kinase Deficiency is ADK (Adenosine Kinase). Affiliated tissues include liver and skeletal muscle, and related phenotypes are macrocephaly and hypertelorism

Disease Ontology : 12 A hypermethioninemia characterized by autosomal recessive inheritance of developmental delay, early-onset seizures, mild dysmorphic features, and characteristic biochemical anomalies, including persistent hypermethioninemia that has material basis in homozygous mutation in the ADK gene on chromosome 10q22.

UniProtKB/Swiss-Prot : 75 Hypermethioninemia due to adenosine kinase deficiency: A metabolic disorder characterized by global developmental delay, early-onset seizures, mild dysmorphic features, and characteristic biochemical anomalies, including persistent hypermethioninemia with increased levels of S-adenosylmethionine and S-adenosylhomocysteine. Homocysteine levels are typically normal.
