This study confirmed the data on the frequency of most recurrence gene mutations and provided evidence that all the genetic alterations, including VHL, PBMR1, BAP1, KDM5C, and SETD2 are related to genetic events resulting in reduced expression of both mRNA and protein, thus indicating loss-of-function and supporting the classification of these genes as tumor suppressors [181]. This evidence concerns the gene BAP1 and neoplasm.
