One T cell clone, clone 6G4 (MAGE-A1 LTQ/A1), strongly recognized all HLA-A∗01:01-positive MM cell lines but produced limited amounts of IFN-γ upon co-culture with early-passage melanoma cell lines and other tumor cell lines of non-hematopoietic origin (Figure S6). The gene discussed is IFNG; the disease is Miyoshi myopathy.
