A Novel c.6766_6767insAA Mutation in the Neurofibromin Gene in a Patient with Neurofibromatosis Type 1-Associated Glioblastoma / 대한소아신경학회지

ABSTRACT

Neurofibromatosis type 1 (NF-1) is an autosomal dominant neurocutaneous syndrome caused by mutations in the neurofibromin gene. NF-1 patients have a high risk of tumors, and optic glioma is the most commonly observed central nervous system tumor in these patients. However, glioblastoma is extremely rare in pediatric NF-1 patients. Here we report the discovery of a novel heterozygous c.6766_6767insAA (p.Ser2256Lysfs*4), pathogenic mutation in the neurofibromin gene in a 17-year-old boy with NF-1-associated glioblastoma.
