The interaction network of BC candidate genes (Figure 2, obtained by the GeneMANIA (https://genemania.org/, accessed on 18 June 2022)) indicates a key role in the following interactions: cooperative expression of genes (40.67%), overall domains of proteins (30.90%), and physical (positional) communications (15.96%), for which the leading role was paired gene–gene mutual influence of KLHL23–ACOT8, MMP3–MMP10, ZSWIM7–ZSWIM1, ZSWIM3–ZSWIM1, and ZSWIM3–ZSWIM7 (the weight indicators are equal 0.43–0.55) (Supplementary Table S12). The gene discussed is MMP3; the disease is breast cancer.
