Can probability of genetic mutation be an indicator of clinical relevance?
NPM1 gene mutation evaluated on a population basis is a valuable and realistic tool to reflect the pathophysiological relevance of cancer. In a comparison of the NPM1 cDNA of human bladder cancer with its consensus sequence, we have found that a higher NPM1 sequence identity in a population is consistent with poor tumor differentiation, advanced tumor stage, and likelihood of recurrence. These data imply that “probability” of NPM1 mutation is an indicator of status of malignancy.
