Of 39 of the 51 sequenced tumours considered to represent MPNST, two were epithelioid MPNSTs and 16 were from patients exhibiting the clinical phenotype of NF‐1, a finding substantiated by detection of germline NF1 mutations in 12/16 patients (Table 2, supplementary material, Table S1, and Figure 1B). This evidence concerns the gene NF1 and malignant peripheral nerve sheath tumor.
