Adaptive mutation - Wikipedia

WebInactivating mutation rate per two wild-type copies of a TSG is r TSG, where TSG can be either APC or TP53. Rate of LOH per two wild-type copies of a TSG is r LOH. Thus, if the crypt is TSG wild type (TSG +/+), it can inactivate the first copy of the tumor suppressor through either mutation or LOH with a joint rate of r TSG + r LOH.
