Abstract
Early onset isolated dystonia (DYT1) is a hereditary neurological movement disease caused by a single amino-acid deletion in torsin A (TOR1A), a gene encoding a membrane-embedded ATPase. In this study, we generated an induced pluripotent stem cell (iPSC) line from fibroblasts of a DYT1 patient by the retroviral transduction of Yamanaka factors. The iPSCs retained the heterozygous TOR1A mutation (p.Glu303del), showed a normal karyotype, expressed pluripotency markers and exhibited the potential to differentiate into three germ layers both in vitro and in vivo. This DYT1 patient-specific iPSC will be used for modeling the dystonia pathophysiology and probably drug screening.
