ABSTRACT
Objective To screen the mutation and analysis its characteristics of SPG4 and SPG3A in Chinese patients with hereditary spastic paraplegia (HSP).Methods Mutation and polymorphism of the SPG4 and SPG3A were screened in the index eases of 26 autesomal dominant families (AD-HSP) and 30 sporadic cases by combination of DHPLC and sequencing analysis, then the index cases of 26 AD-HSP were further confirmed with direct sequencing.Results One novel mutation of SPG4, 1616 + 1g→t, was identified in the index ease from an AD-HSP family.Three symptomatic patients and 2 pre-symptomatic patients were found in this family by sequencing analysis.No mutation of SPG3A was detected.In addition, 8 novel SPG4 polymorphisms and 3 novel SPG3A polymorphisms were identified.Conclusions The study has broadened the mutation and polymorphism spectrums of SPG4 and SPG3A.Mutation of these two genes is less common in this group of patients.
