To develop a molecular signature, matched del(7q) and non\u2010del(7q) tumors identified by FISH or karyotyping from 11 women were profiled with expression arrays. Our analysis using paired <jats:italic>t<\/jats:italic> tests demonstrates this matched design is critical to eliminate the confounding effects of genotype and environment that underlie patient variation. A gene list ordered by genome\u2010wide significance showed enrichment for the 7q22 target region. Modification of the gene list by weighting each sample for percent of del(7q) cells to account for the mosaic nature of these tumors further enhanced the frequency of 7q22 genes. Pathway analysis revealed two of the 19 significant functional networks were associated with development and the most represented pathway was protein ubiquitination, which can influence tumor development by stabilizing oncoproteins and destabilizing tumor suppressor proteins. Array CGH (aCGH) studies determined the only consistent genomic imbalance was deletion of 9.5 megabases from 7q22\u20107q31.1. Combining the aCGH data with the del(7q) UL mosaicism\u2010weighted expression analysis resulted in a list of genes that are commonly deleted and whose copy number is correlated with significantly decreased expression. These genes include the proliferation inhibitor <jats:italic>HPB1<\/jats:italic>, the loss of expression of which has been associated with invasive breast cancer, as well as the mitosis integrity\u2010maintenance tumor suppressor <jats:italic>RINT1<\/jats:italic>. This study provides a molecular signature of the del(7q) UL subgroup and will serve as a platform for future studies of tumor pathogenesis. \u00a9 2009 Wiley\u2010Liss,
