Subsequent multivariate Cox regression analysis identified 14 mitochondria‐related core genes, including NDUFA1, AARS2, IARS2, COX7B, NDUFA2, FARS2, HSPD1, SURF1, NDUFA12, COA3, ISCU, NDUFA11, NDUFA13 and NDUFS7, as key predictors in a prognostic risk model for predicting overall survival (OS) in cervical cancer patients. This evidence concerns the gene IARS2 and cervical cancer.
