Glycoepitopes potentially recognized by MGL may also be present on gangliosides GM2 and GD2 and on lymphatic endothelial structures in lymph nodes and thymus [15,84], but in general, the exposition of terminal GalNAc in healthy human tissues is not common, rather being attributed to pathological conditions, e.g., cancers in the form of Tn antigens (known as tumor-associated carbohydrate antigens—TACAs) [85]. The gene discussed is CLEC10A; the disease is cancer.
