NEW YORK (GenomeWeb News) – Large-scale studies have unearthed a number of cancer-associated genes, but a portion of those genes have tenuous biological links to the disease and appear unlikely to have true correlations with cancer. As a team of researchers led by the Broad Institute's Gad Getz reported in Nature yesterday, mutational heterogeneity across the genome appears to account for the inclusion of such artifacts on large gene lists.
