Other genes candidates associated with sporadic BC include: TP53 (Ch17p13.1), SLC22A1 (Ch11p15.4), PIK3CA (Ch3q26.32), ESR1 (Ch6q25.1-q25.2), RB1CC1 (Ch8q11.23), KRAS (12p12.1), AKT1 (14q32.33), RB1 (Ch13q14.2), PPM1D (Ch17q23.2), MYC (Ch8q24.21), FGFR1 and eventually ERBB2 (Ch17q12), CCND1 (Ch11q13.3), GATA3 (Ch10p14), MAP3K1 (Ch5q11.2) in certain lineages [16,17,18,19,20,21]. Here, RB1 is linked to breast cancer.
