In ADC patients, the correlation between CNVs and PD-L1 expression (clone 28-8) showed that NKX2-1 (p < 0.001) gain was associated with PD-L1 expression low status, and deletion of chr.9q (p = 0.038) was negatively correlated with PD-L1 expression. This evidence concerns the gene NKX2-1 and AIDS dementia complex.
