Chromosome 17 is a hotspot for chromosomal aberrations in breast and ovarian cancer. Candidate oncogenes and tumor suppressors located on this chromosome include OVCA1 and OVCA2, p53, BRCA1, HER2/neu and others. OVCA1 and 2 map to a highly conserved region on human chromosome 17p13.3 that is deleted in 80% of ovarian cancers and shows frequent loss of heterozygosity in breast cancers . OVCA1 is induced by BRCA1 and is closely linked to p53, a well-known tumor suppressor gene. The close linkage of OVCA1 and p53 suggests that coordinated loss of the two genes may lead to ovarian, breast and other tumor types.
