In addition, there was a highly significant association between levels of expression of CDCA7 and DSS (trend test P = 1.22 × 10−8), which maps just 7 kb from the reported 2q31.1 risk SNP (rs1550623), but while there was a robust eQTL association between rs1550623 and CDCA7 in all cancers (trend tests: nominal P = 0.007, FDR adjusted P = 0.09) there was no association in ER+ cancers alone (both P > 0.1). Here, CDCA7 is linked to cancer.
