Abstract:
Grade I invasive ductal breast carcinomas have a specific pattern of genetic aberrations, namely gain of 1q and loss of 16q. This pattern is very similar to the changes seen in invasive lobular breast carcinomas (ILCs). The gene on 16q involved in ILC is known to be E-cadherin (CDH1). This study has investigated whether the same gene is responsible for grade I invasive ductal carcinoma (IDC), using allele imbalance analysis, mutation screening, and immunohistochemistry (IHC). The data suggest that despite the shared pattern of genetic aberrations seen in grade I IDC and ILC, CDH1 is not the target gene in low-grade ductal tumourigenesis.
