Abstract
In the post-genome era, high throughput gene expression profiling has been successfully used to develop genomic biomarker panels (GBP) that can be integrated into clinical decision making. The development of GBPs in the context of personalized medicine is a scientifically challenging and resource-intense process. It needs to be accomplished in a systematic phased approach to address biological variation related to a clinical phenotype (e.g. disease etiology, gender, etc.) and minimize technical variation (noise). Here we present the methodological aspects of GBP development based on the experience of the Cardiac Allograft Rejection Gene Expression Observation (CARGO) study, a study that lead to the development of a molecular classifier for rejection screening in heart transplant patients.
Keywords: Post-genome era, genomics, gene expression profiling, biomarker panels, molecular classifier, heart transplantation, multiorgan dysfunction, personalized medicine

New insights on Pediatric Tumors and Associated Cancer Predisposition Syndromes
Because of the broad spectrum of children cancer susceptibility, the diagnosis of cancer risk syndromes in children is rarely used in direct cancer treatment. The field of pediatric cancer genetics and genomics will only continue to expand as a result of increasing use of genetic testing tools. It's possible that ...read more
