Then, we validated the association of the communities with breast cancer subtypes (Luminal A (LumA) ∖ B (LumB), Her2 and Basal) (Fig. 2C and Additional file 1: Table S1)as well as their association with mutagenic processes independent of the subtyping through the mutation behaviour of the core genes with top degrees. This evidence concerns the gene ERBB2 and breast carcinoma.
