Consolidating the Role of TDP2 Mutations in Recessive Spinocerebellar Ataxia Associated with Pediatric Onset Drug Resistant Epilepsy and Intellectual Disability (SCAR23)

Spinocerebellar Ataxia 23 (SCAR23) is a newly described condition caused by mutations in TDP2 gene. To date, only four patients from two families have been reported, all carrying the same homozygous mutation. We describe a fifth patient, carrying a novel mutation in the same gene, thus confirming the role of TDP2 mutations in determining the disease and defining the main features SCAR23: pediatric onset ataxia and drug-resistant epilepsy and...
