High-Resolution Genomic Profiling of Adult and Pediatric Core-Binding-Factor Acute Myeloid Leukemia Reveals New Recurrent Genomic Alterations

ABSTRACT: To identify cooperating lesions in core-binding-factor acute myeloid leukemia (CBF-AML), we performed single-nucleotide polymorphism (SNP)-array analysis on 300 diagnostic and 41 relapse adult and pediatric leukemia samples. We identified a mean of 1.28 copy number alterations (CNAs) per case at diagnosis in both patient populations. Recurrent minimally deleted regions (MDRs) were identified at 7q36.1 (7.7%), 9q21.13 (5%), 11p13 (2.3%), and 17q11.2 (2%). Recurrent focal gains were identified at 8q24.21 (4.7%) and 11q25 (1.7%), both containing a single non-coding RNA. Recurrent regions of copy-neutral loss-of-heterozygosity were identified at 1p (1%), 4q (0.7%), and 19p (0.7%), with known mutated cancer genes present in the minimally altered region. Analysis of relapse samples identified re
