ERBB2 and breast carcinoma: Similarly, HER2– rs1136201 risk allele G (OR = 1.8691, 95% CI = 1.3417–2.6038, p = 0.002) and the heterozygous genotype AG showed significant association (OR = 2.037, 95% CI = 1.2903–3.2159, p = 0.0023) with breast cancer but the homozygous genotype GG did not display significant association (OR = 2.5946, 95% CI = 0.9876–6.8165, p = 0.0530).
