SNPs NR1I2 rs3732360 (C > T, C > G), rs1054190 (C > T) and rs1054191 (G > A) are described to be linked with change in doxorubicin pharmacokinetics via altering the miRNA mediated post-transcriptional regulation of PXR in Asian (Indian) breast cancer patients [16]. Here, NR1I2 is linked to breast carcinoma.
