In previous studies, single nucleotide polymorphisms in FcgRIIa and FcgRIIIa genes have not only been associated with susceptibility to various diseases such as autoimmune disorders [6,7], infectious diseases [8] and coagulation defects [9], but also with disease progression and responsiveness to immunological therapies, such as mAb therapies [10,11] and cancer vaccinations [12,13]. Here, FCGR3A is linked to cancer.
