How can tumor suppressor genes cause cancer
WebThe p53 gene like the Rb gene, is a tumor suppressor gene, i.e., its activity stops the formation of tumors. If a person inherits only one functional copy of the p53 gene from their parents, they are predisposed to cancer and usually develop several independent tumors in a variety of tissues in early adulthood.

WebTumor suppressor genes: These genes are able to recognize abnormal growth and reproduction of damaged cells, or cancer cells, and can interrupt their reproduction until the defect is corrected. If the tumor suppressor genes are mutated, however, and they do not function properly, tumor growth may occur. WebClassic tumor suppressor genes are defined by mutation in both familial and sporadic forms of cancer. An increasing number of candidate tumor suppressor genes are identified by somatic mutations and have not been associated with genetic predisposition. Examples include BUB1, BUBR1, TGF-βRII, Axin, DPC4, p300, and PPARγ.
