O’Rourke et al. [140] using a native antigen reverse capture microarray for autoantibody profiling in a PCa cohort (n = 41) showed that DFS70/LEDGF (identified as PSIP1 in that study) was one of the top 5 autoantibody signatures in this cohort, and that these signatures differentiate PCa from other malignancies. The gene discussed is PSIP1; the disease is posterior cortical atrophy.
