MalaCards based summary: Dystonia, Dopa-Responsive, Due to Sepiapterin Reductase Deficiency, also known as dopa-responsive dystonia due to sepiapterin reductase deficiency, is related to dystonia and adrenoleukodystrophy, and has symptoms including autosomal dominant inheritance, autosomal recessive inheritance and microcephaly. An important gene associated with Dystonia, Dopa-Responsive, Due to Sepiapterin Reductase Deficiency is SPR (sepiapterin reductase (7,8-dihydrobiopterin:NADP+ oxidoreductase)). Affiliated tissues include brain.

Genetics Home Reference:21 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.

NIH Rare Diseases:41 Sepiapterin reductase deficiency is a type of neurotransmitter disorder. it can also be more broadly classified as an inborn error of metabolism, because it is caused by an error in the pterin metabolism. pterin metabolism plays an important role in making neurotransmitters in the brain, specifically dopamine, serotonin, biopterin, and their metabolites. this deficiency is caused by mutations in the spr gene and is inherited in an autosomal recessive fashion. common symptoms include developmental delay, learning disability, and impaired motor skills. treatment with levodopa has shown much success causing drastic improvements in motor functioning. last updated: 2/18/2009
