The results of our study are not consistent with the findings of Angius et al. and Khaled et al. Angius et al. did not observe statistically significant correlation of BCL11A with the grade of histological malignancy of BC [11], whereas Khaled et al. presented a positive correlation of BCL11A with the grade of histological malignancy of BC [5]. This evidence concerns the gene BCL11A and breast cancer.
