Spearman’s rank correlation tests evaluated the correlation between genetic alterations in MDM2, EWSR1, CDKN2A, and HMGA2 and their AS events. a MDM2, b EWSR1, c HMGA2, d CDKN2A. Expected genetic alterations of CDKN2A, genetic alterations of another three genes showed relatively weak relationships with their AS events
