While CCNE1-amplified tumors are enriched for alterations associated with CIN (such as TP53 and ERBB2), molecular data in the CODEai database are aggregated, and so we are unable to assign TCGA subtypes and assess the relationship of CCNE1 amplification on an individual sample basis. This evidence concerns the gene TP53 and cervical squamous intraepithelial neoplasia.
