Summaries for Tetrahydrobiopterin Deficiency

NIH Rare Diseases : 53 Tetrahydrobiopterin (BH4) deficiency is a neurological condition caused by an inborn error of metabolism. BH4 is a substance in the body that enhances the action of other enzymes. Deficiency of BH4 leads to abnormally high blood levels of the amino acidphenylalanine, and low levels of certain neurotransmitters. Signs and symptoms can range from very mild to severe. Affected newborns appear normal at birth, but may begin to experience neurological symptoms such as abnormal muscle tone; poor sucking and coordination; seizures; and delayed motor development. Without early, appropriate treatment, the condition can cause permanent intellectual disability and even death. BH4 deficiency is caused by mutations in any one of several genes including the GCH1, PCBD1, PTS, and QDPR genes. It is inherited in an autosomal recessive manner.Treatment depends on the genetic cause and severity, and may include a low phenylalanine diet; oral BH4 supplementation; and neurotransmitter replacement.

MalaCards based summary : Tetrahydrobiopterin Deficiency, also known as hyperphenylalaninemia, non-phenylketonuric, is related to hyperphenylalaninemia, bh4-deficient, b and hyperphenylalaninemia, bh4-deficient, a. An important gene associated with Tetrahydrobiopterin Deficiency is GCH1 (GTP Cyclohydrolase 1), and among its related pathways/superpathways are Metabolism and Prolactin Signaling Pathway. The drugs Verapamil and Nitric Oxide have been mentioned in the context of this disorder. Affiliated tissues include brain, endothelial and pituitary, and related phenotypes are Increased shRNA abundance (Z-score > 2) and Increased shRNA abundance (Z-score > 2)

Genetics Home Reference : 25 Tetrahydrobiopterin deficiency is a rare disorder characterized by a shortage (deficiency) of a molecule called tetrahydrobiopterin or BH4. This condition alters the levels of several substances in the body, including phenylalanine. Phenylalanine is a building block of proteins (an amino acid) that is obtained through the diet. It is found in foods that contain protein and in some artificial sweeteners. High levels of phenylalanine are present from early infancy in people with untreated tetrahydrobiopterin deficiency. This condition also alters the levels of chemicals called neurotransmitters, which transmit signals between nerve cells in the brain.
