Of the ten genes, the Parkinson's disease-associated gene PARK2 has been recently described as a tumor suppressor gene in glioblastoma and other malignancies [30], while DLL1, HSD17B3 and ULBP have been reported to be associated with cancer, although not as tumor suppressors [31], [32], [33], [34], [35], [36], [37]. The gene discussed is PRKN; the disease is Parkinson disease.
