Additionally, the GTCG haplotype exhibited a recessive model correlation of 0.38 (p < 0.001) [9]. Amongst our study findings, the chemokine ligand 4 (CCL4) rs10491121 SNP and the AT genotype compared to the AA genotype among those with the luminal A and luminal B subtypes may play a protective role in reducing risk of developing lymph node metastasis with an odds ratio (OR) of 0.298 and 95% confidence interval (CI) of 0.1-0.885 [25]. Here, CCL4 is linked to metastatic malignant neoplasm in the lymph nodes.
