Similarly, the RANKL (rs9533156) risk allele C (OR: 5.000 CI: 2.7280–9.1642, p = 0.0001) and homozygous mutant genotype CC (OR: 11.1818 CI: 3.3299–37.5486, p = 0.0001) were significantly associated with high risk of breast to bone metastasis but the heterozygous genotype TC (OR: 1.4400 CI: 0.4234–4.8972, p = 0.5593) was not associated with disease risk. Here, TNFSF11 is linked to metastasis.
