To compare the GEs of the APOA1/C3/A4/A5 in breast tumors of the age <50 years/ER+/HER2− subgroup between Asians and Caucasians, we retrieved the raw data from the GSE2019420 and GSE4525521 datasets, which included tumors from multiple races. This evidence concerns the gene APOA1 and breast neoplasm.
