We found that copy number alterations of these cancer genes were specific to histotypes as well; e.g. TPM3 amplification in endometrioid tumors; JAK2 deletion in mucinous; RB1 deletion in both clear cell and serous tumors; TP53 and MAP2K4 deletion in mucinous and serous tumors. This evidence concerns the gene RB1 and endometrioid tumor.
