Rs2420946

This SNP is basically a proxy for SNP rs1219648, which represents the SNP in the FGFR2 gene with the strongest association with breast cancer.

Based on a study of 1,049 Chinese breast cancer patients, carriers of risk alleles at three SNPs (rs2981582, rs1219648 and rs2420946) were at 1.36x increased risk for breast cancer (CI: 1.13-1.62, p = 0.001).
