Breast cancer patients with P/LP variants in BRCA1/2 had, approximately, the same age at diagnosis as patients with P/LP variants in other genes, with average ages at diagnosis of 44.9 years (range from 24 to 77, ±11.6) and 46.7 years (range from 18 to 79, ±6.4). This evidence concerns the gene BRCA1 and breast cancer.
