Purpose:
The aim of this study was to screen the possible pathogenic genes of one family with tuberous sclerosis complexes (TSCs).
Patients And Methods:
All family members were examined through detailed clinical evaluations, auxiliary examinations and CT. Then, we selected five members from this TSC family as the test samples. They were analysed by a new exon group sequencing method. Single nucleotide polymorphisms (SNPs) were screened by using databases, such as dbSNP and HAPMAP, and then the candidate genes were selected. Genes were analysed, and finally, the most likely mutation sites were screened. The results were examined by Sanger sequencing.
Results:
In this TSC family, we identified c.913+2T>G, a splicing site mutation in the 9th intron region of TSC1. Family members without TSC did not have this mutation.
Conclusion:
The mutations in the intron regions cannot be ruled out as a pathogenic factor for TSC.
