In the present study, we used bioinformatics tools, such as BioPortal, to analyze the clinicopathological features of ILC in the presence (CDH1-altered ILC) and absence (CDH1-unaltered ILC) of CDH1 alterations, utilizing datasets from The Cancer Genome Atlas (TCGA) and the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC). The gene discussed is CCL27; the disease is breast carcinoma.
