RNF217 and Miyoshi myopathy: In order to get a more profound understanding of the correlation of circRNAs with prognosis in MM, we evaluated the correlation of the top 10 upregulated and top 10 downregulated circRNAs with treatment response as well as survival, and disclosed that circ-PTK2 and circ-RNF217 were correlated with poor treatment response and survival, while circ-AFF2 predicted good treatment response and survival in MM patients.
