In another breast cancer study, it was found that the T-T haplotype of two identified SNPs located in intron 1 of the SLCO1A2 gene, rs4762699 and rs2857468, were highly associated with the risk of life-threatening febrile neutropenia in breast cancer patients treated with docetaxel (along with doxorubicin) [50]. The gene discussed is SLCO1A2; the disease is breast cancer.
