For a person to develop tumor both copies of the gene must be mistake or altered allowing for a loss of function that prevents its from causing degradation of HIF1α in the normal oxygen level as its it normal function. This then allows for the survival of HIF1α that promotes amgiogenesis promoting tumor development.
