In this study, we used a CNV dataset based on GWS to describe the genes (MCM3, EDARADD, Cul5, RBM46, and B3GALT5) that may be associated with the embryonic SNT phenotype and four genes (LOC102185621, LOC102190481, UGP2 and ETNK1) associated with BC. This evidence concerns the gene MCM3 and breast cancer.
