The Cancer of the Genome Atlas (TCGA) database, which includes multi-omics genome-wide profiling data, lists only 34 (out of 770) breast cancer cases from patients of Hispanic and/or Latin American ancestry (21 cases of luminal A subtype, five of luminal B, two of HER2, and six of basal) (https://www.cancer.gov/tcga, accessed 23 March 2023). This evidence concerns the gene ERBB2 and breast carcinoma.
