In this study we aimed to assess the frequency of PDYN gene defects and extend the phenotype of SCA23 patients in a UK ataxia series and also in patients from Greece, Egypt and India.
We previously identified four missense mutations in the prodynorphin gene that cause human neurodegenerative disorder spinocerebellar ataxia type 23 (SCA23).
We have recently identified missense mutations in prodynorphin (PDYN), the precursor to dynorphin opioid peptides, as the cause for spinocerebellar ataxia (SCA23) in Dutch ataxia cases.
