Constitutional NF1 mutations in neurofibromatosis 1 patients with malignant peripheral nerve sheath tumors.

Abstract excerpt

Neurofibromatosis type 1 (NF1) patients have 10% of lifetime risk for developing malignant peripheral nerve sheath tumors (MPNST), one of the most aggressive cancers. We examined the spectrum of constitutional NF1 mutations among 24 NF1 patients with MPNST. We found mutations in 18 patients: four megabase deletions involving the NF1 gene, 13 truncating mutations, and only one missense mutation. One deletion...
