In breast, bladder, and gastric cancer, the high expression of other GPI-anchor biosynthesis glycogenes, such as PIGU, PIGT, and PIGX, is associated with oncogenesis, poor prognosis, and tumorigenesis (Guo et al., 2004; Zhao et al., 2012; Gamage & Hendrickson, 2013; Nakakido et al., 2016). The gene discussed is PIGU; the disease is gastric cancer.
