CUX1 is within the 2.17-Mb CDS of 7q22.1. Copy number analysis of 7q derived from SNP arrays of 35 samples of de novo AML or t-MNs. Thirty-four samples are from primary leukemia samples, and UoCM1 is a cell line derived from the leukemia cells of a patient with de novo AML. Seventeen samples have −7/del(7q) detected by cytogenetic analysis as depicted above the sample identifiers. The percentage of cells exhibiting the abnormality is indicated in brackets. T12 has a cryptic deletion in 7q22.1 not visible by conventional cytogenetic analysis. The CDS spans 49 genes; however, only the genes bordering the CDS are shown for clarity. Data are visualized with Integrated Genome Viewer Version 2.0.⁵⁰  Previously identified commonly deleted segments are shown on the right panel, and genomic coordinates are indicated in build hg19. LOH indicates loss of heterozygosity.
