Genetics Home Reference : 25 Sepiapterin reductase deficiency is a condition characterized by movement problems, most often a pattern of involuntary, sustained muscle contractions known as dystonia. Other movement problems can include muscle stiffness (spasticity), tremors, problems with coordination and balance (ataxia), and involuntary jerking movements (chorea). People with sepiapterin reductase deficiency can experience episodes called oculogyric crises. These episodes involve abnormal rotation of the eyeballs; extreme irritability and agitation; and pain, muscle spasms, and uncontrolled movements, especially of the head and neck. Movement abnormalities are often worse late in the day. Most affected individuals have delayed development of motor skills such as sitting and crawling, and they typically are not able to walk unassisted. The problems with movement tend to worsen over time. People with sepiapterin reductase deficiency may have additional signs and symptoms including an unusually small head size (microcephaly), intellectual disability, seizures, excessive sleeping, and mood swings.

MalaCards based summary : Dystonia, Dopa-Responsive, Due to Sepiapterin Reductase Deficiency, also known as sepiapterin reductase deficiency, is related to dystonia, dopa-responsive and hyperphenylalaninemia, bh4-deficient, a, and has symptoms including seizures, ataxia and tremor. An important gene associated with Dystonia, Dopa-Responsive, Due to Sepiapterin Reductase Deficiency is SPR (Sepiapterin Reductase), and among its related pathways/superpathways are Metabolism and Histidine, lysine, phenylalanine, tyrosine, proline and tryptophan catabolism. The drugs Alprazolam and Promethazine have been mentioned in the context of this disorder. Affiliated tissues include testes, thyroid and brain, and related phenotypes are intellectual disability and delayed speech and language development

Disease Ontology : 12 A dystonia characterized by sustained muscle contractions with diurnal fluctuations, axial hypotonia, oculogyric crises, delays in motor and cognitive development and severe dopamine and serotonin deficiencies that has material basis in mutation in the SPR gene on chromosome 2p resulting in sepiapterin reductase deficiency.

NIH Rare Diseases : 52 Sepiapterin reductase deficiency is a neurometabolic disorder characterized by a pattern of involuntary sustained muscle contractions known as dystonia . Other common features include axial hypotonia , oculogyric crises , and delays in motor and cognitive development. The condition is caused by mutations in the SPR gene . It is inherited in an autosomal recessive fashion. Treatment with levodopa (L-dopa) in combination with carbidopa has shown much success causing drastic improvements in motor functioning.

OMIM : 56 SPR deficiency results in neurologic deterioration due to severe dopamine and serotonin deficiencies in the central nervous system caused by a defect in BH4 synthesis. Clinically, affected individuals show an L-DOPA-responsive, diurnally fluctuating movement disorder usually associated with cognitive delay and severe neurologic dysfunction. BH4 is a required cofactor for the synthesis of the neurotransmitters dopamine and serotonin. BH4 is also a required cofactor for phenylalanine hydroxylase (PAH; 612349), but patients with SPR deficiency do not exhibit overt hyperphenylalaninemia. The lack of hyperphenylalaninemia distinguishes SPR deficiency from other disorders of BH4 synthesis (see, e.g., HPABH4A, 261640). However, the neurologic phenotype of SPR deficiency resembles the other BH4-deficient disorders (summary by Bonafe et al., 2001 and Friedman et al., 2012). Another form of dopa-responsive dystonia (DTY5; 128230) is caused by mutation in the gene encoding GTP cyclohydrolase I (GCH1; 600225), which is also a component of the biopterin synthetic pathway. (612716)

UniProtKB/Swiss-Prot : 73 Dystonia, DOPA-responsive, due to sepiapterin reductase deficiency: A form of DOPA-responsive dystonia. In the majority of cases, patients manifest progressive psychomotor retardation, dystonia and spasticity. Cognitive anomalies are also often present. The disease is due to severe dopamine and serotonin deficiencies in the central nervous system caused by a defect in BH4 synthesis. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures.
