Spinocerebellar ataxia type 3 (SCA3) is a dominantly inherited neurodegenerative disease caused by a CAG-repeat expanding mutation in ATXN3. We generated induced pluripotent stem cells (iPSCs) from a SCA3 patient by electroporation of dermal fibroblasts with episomal plasmids encoding L-MYC, LIN28, SOX2, KLF4, OCT4 and short hairpin RNA targeting P53. The resulting iPSCs had normal karyotype, were free of genomically integrated episomal plasmids, expressed pluripotency markers, could differentiate into the three germ layers in vitro and retained the disease-causing ATXN3 mutation. This iPSC line could be useful for the investigation of SCA3 disease mechanisms.

Widespread white matter (WM) microstructural abnormalities have been reported in patients with spinocerebellar ataxia type 3 (SCA3) using diffusion tensor imaging (DTI), whereas the ability of DTI to detect WM degeneration over short-term period remains insufficiently explored. Additionally, WM dysfunction remains entirely unknown in this disease. This study aims to investigate WM structural and functional alterations in SCA3, and provide promising progression biomarkers for short-term clinical trials.

The expansion of glutamine residue track (polyQ) within soluble proteins (Q proteins) is responsible for nine autosomal-dominant genetic neurodegenerative disorders. These disorders develop when polyQ expansion exceeds a specific pathogenic threshold (Q) which is unique for each disease. However, the pathogenic mechanisms associated with the variability of Q within the family of Q proteins are poorly understood.

Background: The regulatory role of the apolipoprotein E (APOE) ε4 allele in the clinical manifestations of spinocerebellar ataxia type 3 (SCA3) remains unclear. This study aimed to evaluate the impact of the APOE ε4 allele on cognitive and motor functions in SCA3 patients.
Methods: This study included 281 unrelated SCA3 patients and 182 controls.

Spinocerebellar ataxias (SCAs) are a diverse and heterogeneous group of inherited neurodegenerative disorders marked by progressive ataxia and cerebellar degeneration. This case report details an 11-year-old Indian boy with childhood-onset ataxia and severe sensorineural hearing loss, a rarely reported concomitance in pediatric neurology. Genetic analysis identified a unique heterozygous 3' splice site variant in the PNPT1 gene (c.
