From NCBI Gene: This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. [provided by RefSeq, Jul 2008]

Ninety biomarkers were measured using a series of multiplexed immunoassays and results analyzed by the EDRN data management center splitting the cases and controls into training and validation sets, excluding subjects with DCIS or atypical hyperplasia from the training phase. We found little evidence that any of these markers can discriminate women with invasive cancer from those with benign breast conditions.

Amplification and/or overexpression of the ERBB2 gene has been reported in numerous cancers, including breast and ovarian tumors. Studies have suggested that ERBB2 overexpression represented a major negative prognostic indicator for patients with several human cancers, including endometrial carcinomas
Despite many promising new markers for ovarian cancer, CA125 remains the single best biomarker in the phase II and phase III specimens tested in this study.
