ABSTRACT
OBJECTIVE@#To identify pathogenic mutation in a Chinese family affected with hereditary spastic paraplegia (HSP) through genetic testing and a follow-up survey.@*METHODS@#Whole exome sequencing was performed on DNA samples of two patients and one unaffected member to screen candidate mutations. Sanger sequencing was used to validate the suspected mutations in all ten family members.@*RESULTS@#Four patients and three asymptomatic members (under 25 years old) carried a c.1771T>C mutation of the KIAA0196, while the other three asymptomatic members (over 40 years old) did not carry the mutation. The mutation was predicted to be "affect protein function", "probably damaging" and "disease causing" by SIFT, PolyPhen-2 and Mutation Taster, respectively. Three asymptomatic carriers were followed up and one of them developed HSP one year later, while the other two had no signs of the disease yet.@*CONCLUSION@#The clinical phenotype of the c.1771T>C mutation of KIAA0196 has a considerable heterogeneity and this mutation may be a common pathogenic site of KIAA0196 mutations among Chinese patients with hereditary spastic paraplegia.
