A hypoxia inducible pathway that deviates from what its normal course should be. Mutations in the von Hippel-Lindau (Vhl), the E3 ubiquitin ligase which targets Hif alpha for degradation under normoxic conditions, lead to a constitutively active pathway regardless the levels of oxygen. Mutations in Vhl and a number of other genes have been implicated in renal cancers.
