TRAJ24 and thymoma: The diversity of TCR represented by the Gini index was mostly unchanged between them (Supplementary Fig. 5a), but the composition rate of a TCR alpha chain J, TRAJ24, was high in MG (Padj = 9.6 × 10−4; Supplementary Fig. 5b), and especially the TRAJ24-TRAV13-2 combination was 7.50-fold more frequent in MG-thymoma (Supplementary Fig. 5c).
