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…
REEP1 mutation spectrum and genotype/phenotype correlation in hereditary spastic paraplegia type 31.
Contains fulltext : 71291.pdf (Publisher’s version ) (Closed access) Mutations in the receptor expression enhancing protein 1 (REEP1) have recently been reported to cause autosomal dominant hereditary spastic paraplegia (HSP) type SPG31. In a large collaborative effort, we screened a sample of 535 unrelated HSP patients for REEP1 mutations and copy number variations. We identified 13 novel and 2 known REEP1 mutations in 16 familial and sporadic patients by direct sequencing analysis. Twelve out of 16 mutations were small insertions, deletions or splice site mutations. These changes would result in shifts of the open-reading-frame followed by premature termination of translation and haploins…
