Includes bibliographical references. / Spinocerebellar ataxia type 7 (SCA7) is an inherited neurodegenerative disease caused by a pathogenic expansion of a CAG repeat within the ataxin 7 gene, resulting in an expanded polyglutamine tract in the ATXN7 protein. SCA7 patients suffer from selective degeneration of cerebellar Purkinje neurons and retinal photoreceptors, which leads to the development of various neurological symptoms, and blindness. SCA7 is considered to be a relatively rare disease, but South Africa has an increased prevalence of the SCA7 due to a founder effect within the black African population. In this study, three distinct but complementary approaches were taken to investigate SCA7 in South Africa, with the aim of estimating the prevalence of the disease, developing improved approaches for molecular diagnostic testing, and establishing a model for in vitro studies of pathogenesis.
