The identification of disease-causing genetic defects is critically important for treatment options. In last decade, next-generation sequencing (NGS)-based methods has enabled the rapid genetic screening and the discovery of new genetic defects in PIDs. In this study, we investigated causative mutations in patients with PID by NGS. Methods: We applied whole-exome sequencing in 8 PID patients. Detected mutations by NGS were validated by Sanger sequencing. Results: We made a genetic diagnosis in 5 of 8 (63%) patients, including 3 novel disease-causing variants. The identified mutations were found in RAG1, RAG2, JAK3, RFXANK, and CYBA genes. Conclusions: Our results show that whole-exome sequencing can facilitate the genetic diagnosis of the patients with PID.eninfo:eu-repo/semantics/openAccessPrimary ImmunodeficiencyNext-Generation SequencingWhole-Exome SequencingArticle12433406023WOS:0005179640000012-s2.0-85082534502Q410.1089/ped.2019.1097Q3
