Fas‐associated via death domain (FADD) and tyrosine 3‐monooxygenase/tryptophan 5‐monooxygenase activation protein zeta (YWHAZ) were also highly specific connected in the BRCA network, while both phosphatidylinositol‐4,5‐bisphosphate 3‐kinase catalytic subunit beta (PIK3CB) mutation in CESC, and phosphoinositide‐3‐kinase regulatory subunit 1 (PIK3R1) mutation in UCEC controlled the expression of BCL2L1. X‐ray repair cross‐complementing 6 (XRCC6), N‐myristoyltransferase 1 (NMT1) and caspase 3 (CASP3) in OV showed specific downregulated expression. Here, PIK3R1 is linked to cervical squamous cell carcinoma.
