WebThis mutation disrupts the function of the VHL protein, particularly its ability to target HIF-2α to be broken down. As a result, HIF accumulates in cells even when adequate oxygen is available. The presence of extra HIF leads to the production of red blood cells when no more are needed, which leads to an excess of these cells in the bloodstream. WebMutations in any of the genes in the HIF pathway could lead to changed proteins, abnormalities in the degradation of HIF-α and, ultimately, result in increased …
