Abstract

Purpose To investigate the incidence rate of hereditary disease in patients with medulloblastoma. 
Methods The genetic reports of 129 patients with medulloblastoma from January 2016 to December 2019 were retrospectively analyzed. A panel sequence of 39 genes (Genetron Health) were used for all patients to evaluate the tumor subgroup. Four genes (TP53, APC, PTCH1, SUFU) were screened to routinely rule out germline mutation. 
Results Five patients (3.9%) were found with hereditary disease, and all belonged to the sonic hedgehog (SHH) subgroup. Two patients were retrospectively diagnosed with Gorlin–Goltz disease with germline PTCH1 and SUFU mutations. One patient (PTCH1 mutation) accepted whole craniospinal irradiation and had scalp nevoid basal cell carcinoma 5 years later. The other patient (SUFU mutation) accepted chemotherapy and had local tumor relapse 1 year later. Three patients were diagnosed with Li–Fraumeni syndrome and carried the TP53 mutation; all three patients died. One of the patients had bone osteosarcoma, while all three had early tumor relapse. 
Conclusion Patients with SHH medulloblastoma should routinely undergo genetic testing. We propose that whole genome, whole exome sequence, or custom-designed panel-targeted exome sequencing should be performed.
