Analysis of 100 HSP Exomes and Characterization of Mutations in Known Autosomal Dominant Genes (P05.166)

Objective: Comprehensive screening of all known autosomal dominant HSP genes in a large cohort of patients. Background Hereditary spastic paraplegias comprise a group of clinically and genetically heterogeneous neurodegenerative disorders that share the common clinical feature of lower limb spastic paraplegia. Ten genes causing autosomal dominant HSP are known to date, together explaining about 60% of cases. Knowledge about frequency of HSP subtypes and genotype-phenotype correlation is limited by the fact that most screenings so far are biased due to phenotypic pre-selection of the study cohort or inhomogeneous a priori genetic diagnostic testing. Design/Methods: We have screened a large c…
