Amplified and overexpressed gene in colorectal cancers

摘要

This invention relates to methods to diagnose colon cancer and other proliferative diseases. Gene 26#77 is identified herein as a novel oncogene. Methods are provided for diagnosing and treating a disease or disorder characterized by amplification of the 26#77 gene and/or overexpression of 26#77 gene products. The 26#77 gene is located on chromosome 20q13.2, a region whose amplification is associated with a poor cancer prognosis. The 26#77 gene is amplified and 26#77 RNA and protein are overexpressed in 60% of colorectal cancers.
