FGFR2 and breast cancer: Three previously unreported variants were associated with breast cancer nodal status in BRCA1 carriers: SNPs at 4q24 in the TET2 gene, at 5q32 in the SH3RF2 gene and at 7p22 in an intron of NXPH1. For BRCA2 carriers, only SNPs in FGFR2 and TOX3 exhibited associations at P <10−6 with breast cancer nodal status or histological grade.
