In fact, WTAP overexpression is an important risk factor in many tumours.19 WTAP is widely expressed in various tissues and plays an important role in cell cycle regulation, RNA alternative splicing, m6A methylation modification, x‐chromosome inactivation, eye development, regulation of physiological balance and other physiological processes.20 The role of WTAP in GC is currently rarely reported and controversial. Here, WTAP is linked to neoplasm.
