title: Evaluation of PARVG located on 22q13 as a candidate tumor suppressor gene for colorectal and breast cancer.
abstract: Colorectal cancer (CRC) and breast cancer constitute common neoplasms in Western countries and leading causes of cancer-related death. Development and progression of both malignancies occur as a multistep process, requiring the activation of oncogenes and the inactivation of several tumor suppressor genes. Our group has recently identified a minimal region of deletion on 22q13 involved in CRC and breast cancer patients, which is highly indicative of the existence of a tumor suppressor gene (or genes). We performed mutation analysis of the PARVG gene, one of the genes present on the 22q13 region of interest, which has been previously demonstrated to have a reduced expression in some cancer cell lines. We have identified several DNA variants that are not compatible with pathogenic mutations. Accordingly, PARVG appears not to be a tumor suppressor gene involved in CRC and breast cancer development and progression.
