rs1024611, also known as the -2578A>G SNP due to its position in the promoter of the monocyte chemoattractant protein-1 MCP-1 CCL2 gene, influences the production of its corresponding protein, a chemokine involved in inflammatory responses. In a study focusing on 679 apparently healthy siblings of people with premature heart disease, investigators found that carriers of an rs1024611(C) allele - oriented as in dbSNP, not as published - independently predicted the risk of exercise induced ischemia in general. The odds ratio was reported to be 1.86 (CI: 1.14-3.04, p=0.014), regardless of race, age, sex and other factors. However, it is not clear if this risk carries over to individuals who lack siblings with heart disease. discussed in the 23andMe blog as being relevant to HIV rs1024611 is not associated with systemic sclerosis in a multicenter study of 345 European patients tuberculosis Association study of functional genetic variants of innate immunity related genes in celiac disease.
