BIRC2 and tumor of salivary gland: The genes considered were Birc2, Birc3, Cep126, Maml2, Yap1. Of these, Birc2 and Birc3 are apoptosis inhibitors [15], Maml2 is a Mastermind-like, nuclear coactivator of the Notch receptor occurring in salivary gland tumours as an oncogenic fusion protein [16] and Yap1 is a well-established oncogene [17].
