Abstract: The abnormal changes of tumor suppressor genes such as deletion mutant, transcription inactivation or silence on human chromosome 3p (pter) were considered as a key step which was closely related to the tumorigenesis of several kinds of cancers, especially clear cell renal cell carcinoma, one kind of renal cancer. And on this basis, it has been confirmed that the deletion and downregulation of multiple 3p genes such as VHL, RASSF1A, SEMA3B, SETD2, PBRM1, NPRL2 and so on, play a vital important role in the tumorigenesis and development of clear cell renal cell carcinoma. And they provide a further way to explain the molecular mechanism of the tumorigenesis of kidney cancer. However, when the regulatory pathway and mechanism research of some genes were known to us, the other genes, especially those newly founded, which were still not clear and need to be further investigated.
