BRCA1 and breast cancer: This list supports previously well-studied breast cancer genes, such as the BRCA1 (breast cancer breast cancer 1, early onset) associated RING (really interesting new gene) domain 1 gene (BARD1) [60,61], the mucin 1 (MUC1) [62,63] or cofilin-1 genes (CFL1) [64,65], but also suggest novel candidates that warrant further investigation in breast cancer.
