In the human cases we found one patient (with multiple germline samples sequenced, PD25652b/e/f) with a pathogenic complex TP53 mutation (11 bp deletion + 5 bp insertion; ClinVar ID: 12381) which is in keeping with a previous case report outlining the development of mucosal melanoma in a Li Fraumeni syndrome patient (Table 2)50. Here, TP53 is linked to Li-Fraumeni syndrome.
