Luminal HER2 negative tumors. Homo sapiens

Early age patients less than 36 years represent 4% of breast cancer cases and have a higher probability of being BRCA1/2 mutation carriers. There are indications that tumors from young patients are biologically distinct from older women, however, these tumors have been less studied. Our aim was to identify somatic mutations in luminal tumors from BRCA1/2 wild type young breast cancer patients.
