    Hyperphenylalaninemia, BH4-deficient, B (HPABH4B)2 Publications
    The disease is caused by variants affecting the gene represented in this entry.
    Disease descriptionA disease characterized by malignant hyperphenylalaninemia due to tetrahydrobiopterin deficiency, and defective neurotransmission due to depletion of the neurotransmitters dopamine and serotonin. The principal symptoms include: psychomotor retardation, tonicity disorders, convulsions, drowsiness, irritability, abnormal movements, hyperthermia, hypersalivation, and difficulty swallowing. Some patients may present a phenotype of intermediate severity between severe hyperphenylalaninemia and mild dystonia. In this intermediate phenotype, there is marked motor delay, but no mental retardation and only minimal, if any, hyperphenylalaninemia.

    Dystonia, dopa-responsive (DRD)15 Publications
    The disease is caused by variants affecting the gene represented in this entry.
    Disease descriptionA form of dystonia that responds to L-DOPA treatment without side effects. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures. DRD typically presents in childhood with walking problems due to dystonia of the lower limbs and worsening of the dystonia towards the evening. It is characterized by postural and motor disturbances showing marked diurnal fluctuation. Torsion of the trunk is unusual. Symptoms are alleviated after sleep and aggravated by fatigue and exercise.

    Up-regulated by IFNG/IFN-gamma, TNF, IL1B/interleukin-1 beta, bacterial lipopolysaccharides (LPS) and phenylalanine, and down-regulated by dibutyryl-cAMP, iloprost and 8-bromo-cGMP in HUVEC cells. Up-regulation of GCH1 expression, in turn, stimulates production of tetrahydrobiopterin, with subsequent elevation of endothelial nitric oxide synthase activity. Cytokine-induced GCH1 up-regulation in HUVECs in response to TNF and IFNG/IFN-gamma involves cooperative activation of both the NF-kappa-B and JAK2/STAT pathways. Also up-regulated by hydrogen peroxide in human aorta endothelial cells (HAECs).7 Publications

    <p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iB8A0CB344C598B9A

    <p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P30793
    Secondary accession number(s): Q6FHY7, Q9Y4I8
    <p>This subsection of the 'Entry information' section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification ('Last modified'). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical%5Fand%5Fisoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: July 1, 1993
