The chromosomal passenger complex (CPC) plays a pivotal role in the regulation of cell division. Therefore inherited CPC variability could influence tumor development. The present candidate gene approach investigates the relationship between single nucleotide polymorphisms (SNPs) in genes encoding key CPC components and breast cancer risk. Fifteen SNPs in four CPC genes (INCENP AURKB BIRC5 and CDCA8) were genotyped in 88,911 European women from 39 case-control studies of the Breast Cancer Association Consortium. Possible associations were investigated in fixed-effects meta-analyses. The synonymous SNP rs1675126 in exon 7 of INCENP was associated with overall breast cancer risk (per A allele OR 0.95 95% CI 1.02-1.10, p=0.0002). Two genotyped SNPs in BIRC5 were associated with familial breast cancer risk (top SNP rs2071214: per G allele OR 1.12, 95% CI 1.04-1.21, p=0.002). The data suggest that INCENP in the CPC pathway contributes to ER negative breast cancer susceptibility in the European population. In spite of a modest contribution of CPC inherited variants to the total burden of sporadic and familial breast cancer, their potential as novel targets for breast cancer treatment should be further investigated.
