Tiered genetic testing reveals CACNA1A allelic series and RNA modeling elucidates repeat expansion mechanism in an Indian spinocerebellar ataxias cohort
Spinocerebellar ataxias (SCAs) represent a heterogeneous group of neurodegenerative disorders with significant diagnostic challenges, particularly in genetically underrepresented populations. While tiered genetic testing approaches have been previously applied in Indian cohorts, diagnostic gaps persist with appro...
