Cancer/testis (CT) genes are mainly expressed in the testis with a significant upregulation during oncogenesis (Wang et al., 2016) Testis‐expressed 19 (TEX19) (OMIM# 615647) is one such mammalian‐specific CT genes that is unique for humans and expressed in adult testis and undifferentiated embryonic stem cells and primordial germ cells (Kuntz et al., 2008; Wang et al., 2001). Here, TEX19 is linked to cancer.
