IL6 and Alzheimer disease: Our study of IL-6/rs2069837 showed that A/G genotype was more susceptible to AD (1.933-fold increased risk) than A/A genotype, and that the combined A/G-G/G genotype raised AD risk by 1.856 times compared to patients with A/A genotype, which is the first to evaluate the associations of IL-6/rs2069837 and the risk of AD in Chinese children.
