Similarly, rs17530068 at 6q14 was associated with breast cancer (OR = 1.12; P = 1.1 × 10(-9)), and with both ER-positive (OR = 1.09; P = 1.5 × 10(-5)) and ER-negative (OR = 1.16, P = 2.5 × 10(-7)) disease.
Using the chi-squared (χ<sup>2</sup>) test and genetic model analysis, we found an association with BC for four SNPs (rs616488 (1p36.22/PEX14), rs6678914 (1q32.1/LGR6), rs17530068 (6q14/unknown) and rs6001930 (22q13.1/MKL1)) at a 5% level.
Results showed that in northwest Chinese Han population, SNP rs17530068 (LOC105377871) increases the risk of breast cancer and SNP rs4784227 (CASC16) promotes lymph node metastasis in breast cancer patients.
