Recent genome-wide association studies identified 11 single nucleotide polymorphisms (SNPs) associated with breast cancer (BC) risk. We investigated these and 62 other SNPs for their prognostic relevance. Confirmed BC risk SNPs rs17468277 (CASP8), rs1982073 (TGFB1), rs2981582 (FGFR2), rs13281615 (8q24), rs3817198 (LSP1), rs889312 (MAP3K1), rs3803662 (TOX3), rs13387042 (2q35), rs4973768 (SLC4A7), rs6504950 (COX11) and rs10941679 (5p12) were genotyped for 25 853 BC patients with the available follow-up; 62 other SNPs, which have been suggested as BC risk SNPs by a GWAS or as candidate SNPs from individual studies, were genotyped for replication purposes in subsets of these patients. Cox proportional hazard models were used to test the association of these SNPs with overall survival (OS) and BC-specific survival (BCS). For the confirmed loci, we performed an accessory analysis of publicly available gene expression data and the prognosis in a different patient group. One of the 11 SNPs, rs3803662 (TOX3) and none of the 62 candidate/GWAS SNPs were associated with OS and/or BCS at P<0.01. the="" genotypic-specific="" survival="" for="" rs3803662="" suggested="" a="" recessive="" mode="" of="" action="" [hazard="" ratio="" (hr)="" of="" rare="" homozygous="" carriers="1.21;" 95%="" ci:="" 1.09-1.35,="" p="0.0002" and="" hr="1.29;" 95%="" ci:="" 1.12-1.47,="" p="0.0003" for="" os="" and="" bcs,="" respectively].="" this="" association="" was="" seen="" similarly="" in="" all="" analyzed="" tumor="" subgroups="" defined="" by="" nodal="" status,="" tumor="" size,="" grade="" and="" estrogen="" receptor.="" breast="" tumor="" expression="" of="" these="" genes="" was="" not="" associated="" with="" prognosis.="" with="" the="" exception="" of="" rs3803662="" (tox3),="" there="" was="" no="" evidence="" that="" any="" of="" the="" snps="" associated="" with="" bc="" susceptibility="" were="" associated="" with="" the="" bc="" survival.="" survival="" may="" be="" influenced="" by="" a="" distinct="" set="" of="" germline="" variants="" from="" those="" influencing="">
