Meanwhile, the arm-level amplifications of chr.1q (p = 0.012) and deletions of chr.1p (p = 0.041), chr.5q (p = 0.007), and chr.12p (p = 0.028) were negatively correlated with PD-L1 (clone 22C3) expression in ADC, and only amplification of chr.12p (p = 0.044) was associated with PD-L1 positive status (Supplementary Table S4). Here, CD274 is linked to AIDS dementia complex.
