IR, inter-region (i.e. not matched to a tumour region defined within the lung TRACERx study). + Detected in the majority of cells; # Detected in a subset of cells. Detection of both IgK and IgL light chain expression by immunohistochemistry is indicated with the minor light chain shown in brackets.
