Abstract: Combination analyses of a variety of bone, soft tissue and prostate tumors were done using array-based CGH, Spectral Karyotyping (SKY) and expression microarrays. We identified quantitative genomic alterations that were associated with expression changes and adverse clinical outcome. Microarray-based comparative genomic hybridization (CGH) is a novel technique for rapid quantification of human DNA copy number (gains and losses). This tool is useful for the detection of chromosomal aberrations in genetic disorders and amplification of specific genes in cancer. Several approaches were used until now including hybridization to P1, PAC or BAC clones or to cDNA-based arrays. The Jewish population has been valuable for understanding many genetic disorders due to its unique structure and origin. In recent years, founder mutations associated with major forms of cancers in Jews were detected, including high frequency mutations, which confer high risk for breast and breast-ovarian cancers, and small, but significantly increased risk to colon cancer. We have recently identified a novel founder mutation in the RNASEL gene, 471delAAAG, in 2-3% of Ashkenazi Jews. This is the first null mutation associated with an increased risk and earlier onset of PRCA in Ashkenazi Jewish men. Cancer-associated germ-line mutations in the Jewish population are important for early detection and better patient care and will likely increase our understanding of the genetic basis of common cancers in the general population.
