Segawa Syndrome, Autosomal Recessive

Description

Segawa syndrome is an autosomal recessive neurologic disorder characterized by onset in infancy of dopa-responsive dystonia. There are 2 main phenotypes: one is a severe complex encephalopathy apparent in the perinatal period, with diurnal fluctuations and autonomic disturbances, and the other shows a less severe course with onset in the first year of life of a progressive hypokinetic-rigid syndrome and generalized dystonia. The less severe type shows a better response to levodopa compared to the more severe type (summary by Stamelou et al., 2012).See also infantile parkinsonism-dystonia syndrome (OMIM ), caused by mutation in the SLC6A3 gene (OMIM ).
