Most glioblastomas are not inherited. They usually occur sporadically in people with no family history of tumors. However, they can rarely occur in people with certain genetic syndromes such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. All of these conditions are inherited in an autosomal dominant manner.[1][3]
