Thus, on the one hand, our data corroborate the findings of Bizzaro et al. [20] and Mahler et al. [9], who detected very low frequencies of anti-LEDGF/p75 autoAbs (DFS70) by IFA (<2%) or none at all by chemiluminescence immunoassay in tumor patients [9,20]. The gene discussed is PSIP1; the disease is neoplasm.
