Exome sequencing in paediatric patients with movement disorders.

Background: Movement disorders are a group of heterogeneous neurological diseases including hyperkinetic disorders with unwanted excess movements and hypokinetic disorders with reduction in the degree of movements. The objective of our study is to investigate the genetic etiology of a cohort of paediatric patients with movement disorders by whole exome sequencing and to review the potential treatment implications after a genetic diagnosis.

Results: We studied a cohort of 31 patients who have paediatric-onset movement disorders with unrevealing etiologies.
