The mRNA levels of BRCA2 were significantly increased in patients with invasive ductal breast carcinoma and invasive lobular breast carcinoma, with fold changes of 3.214 and 2.124, and p values of 1.46 × 10−25 and 9.36 × 10−9, respectively (Table 1). This evidence concerns the gene BRCA2 and invasive lobular breast carcinoma.
