Generation of induced pluripotent stem cell line (ZZUi004-A) from urine sample of a patient with spinocerebellar ataxia type 3.

Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the region of the ATXN3 gene. The main feature of SCA3 is progressive ataxia, which affects balance, gait, and speech. Urine cells (UCs) of a SCA3 patient were successfully translated to induced pluripotent stem cells (iPSCs) by using the Sendai virus delivery system. ZZUi004-A cell line may provide a robust platform for further study of SCA3 pathogenesis as well as drug testing and gene therapy research.
