No significant differences indistribution of MCP-1 −2518*G allele were observed between patients with SSc and healthy controls (P > .05).Furthermore, MCP-1 −2518 GG homozygotes and MCP-1 −2518*G allele carriers weresimilarly represented among SSc patients and healthycontrol subjects (P > .05). This evidence concerns the gene CCL2 and systemic sclerosis.
