The CSI of each MM patient was calculated using the following formula: CSI = (0.18734 × UBE2T expression) + (−0.33100 × CDKN1A expression) + (−0.29107 × EFNA1 expression) + (−0.38349 × RNF121 expression) + (0.40942 × UBE2G2 expression) + (0.23662 × ANXA2 expression) + (0.21746 × DMC1 expression) + (0.30648 × ENO1 expression) + (−0.10139 × ALDH2 expression). Here, UBE2T is linked to Miyoshi myopathy.
