What mechanisms explain how IDH1/IDH2 mutations with reduced enzymatic activity lead to better patient outcomes?

PARTIALLY ADDRESSED

The abstract shows that IDH mutations reduce protein enzymatic activity yet paradoxically correlate with improved prognosis. This counterintuitive finding suggests unknown mechanisms by which metabolic dysfunction may actually benefit patients or reflect less aggressive tumor biology.
