No association between CCL2 gene polymorphisms and risk of inflammatory demyelinating diseases in a Korean population

Inflammatory demyelinating disease (IDD), which includes multiple sclerosis (MS) and neuromyelitis optica (NMO), affects the central nervous system. Chemokine ligand 2 (CCL2/MCP-1) is considered an important contributor to the development or progression of IDD. However, genetic association studies of Asian populations are lacking. In this study, we investigated a possible association between CCL2 polymorphisms (rs1024611, rs28730833, and rs2857657) and a Korean population (178 IDD patients and 237 healthy controls) using multiple logistic regression models. However, we did not find any association, which was consistent with other studies in Caucasian populations. In conclusion, our results suggest that CCL2 variants may not contribute to the pathogenesis of IDD.
