[[rs1434536]] is a SNP reported to potentially represent a miR-125b binding site.

A study of 459 probands from a [[breast cancer]] affected sibling pair cohort were recruited from the ECOG study, and in conjunction with 1,145 patient samples from the CGEMS study, led to the conclusion that [[rs1434536]] was associated with increased risk for [[breast cancer]]. The odds ratios for [[rs1434536]](A;G) and (A;A) individuals were 1.29 (CI: 0.95-1.74) and 1.94 (CI: 1.40-2.71), respectively (p=1.6x10e-4).{{PMID|19738052|OA=1
