MSS/p53− tumors (36% of cases) present overlap with the CIN group from TCGA, showing the highest prevalence of p53 mutations and recurrent focal amplifications of tyrosine kinase receptors, like ERBB2 or cell-cycle modulators, like CCNE1 or CCND1. This evidence concerns the gene TP53 and cervical squamous intraepithelial neoplasia.
