In total, we identified five PD-L1 splicing variants: PD-L1v178 from the JFCR-119 baseline; PD-L1v178, PD-L1v174, PD-L1v242 (same as Fig. 1 D), and PD-L1v265 from the JFCR-119 resistant tumor; and PD-L1v229 from the JFCR-151 relapsed tumor (Fig. S1, G–K; and Fig. S2). Here, CD274 is linked to neoplasm.
