T-C7 was scattered around T-C6 and was relatively high in immunoglobulins such as IGHG3 (immunoglobulin heavy constant gamma 3 involved in B-cell activation) and IGKC (immunoglobulin kappa constant, Figures 5F, G), which are markers secreted by tumor-infiltrating B cells (22, 23). The gene discussed is IGHG3; the disease is neoplasm.
