FCGRT is also known as FcRn, which encodes a receptor that binds the Fc region of monomeric immunoglobulin G. Previous studies reveal that FCGRT plays a crucial role in anti-tumor immunosurveillance (56) and lack of FCGRT could impair development and function of innate immune cells leading to poor prognosis of cancer (57). Here, FCGRT is linked to cancer.
