Traditional mutation detection methods require Sanger sequencing of all exons, which is time-consuming and laborious, and prone to missed detection errors. Therefore, this study used Ion Torrent sequencing technology to quickly and accurately detect NF1 gene mutations, providing a basis for clinical diagnosis and treatment. The study will recruit 20 NF1 patients, extract their peripheral blood DNA and establish a library, and then perform Ion Torrent sequencing. Using bioinformatics software to perform quality control, mutation detection and annotation analysis on the data, finally to obtain the mutation information of each patient. By comparing the variation between patients and normal populations, selecting potential sites related to NF1 pathogenesis. The study is expected to quickly and accurately detect NF1 gene mutations and provide help for the diagnosis and treatment of NF1.Keywords: type I neurofibromatosis, NF1 gene mutation, Ion Torrent sequencing technology.
