Sixty-seven patients (8.1%) had documented CPS, with the most prevalent being neurofibromatosis type 1 (NF-1; N=25), followed by tuberous sclerosis (N=10), neurofibromatosis type 2 (NF-2; N=7), and Li-Fraumeni syndrome (N=7) (Table S2). This evidence concerns the gene NF1 and NF2-related schwannomatosis.
