Tan et al. [25] assessed a total of 10 SNPs among 612 sporadic late-onset AD (LOAD) patients and 612 control subjects from northern Han Chinese, including 2 in BIN1 (rs7561528 and rs744373), 2 in ABCA7 (rs3752246 and rs3764650), 3 in the MS4A gene cluster (rs4938933, rs610932, and rs670139), and 1 each in CD2AP (rs9349407), CD33 (rs3865444), and EPHA1 (rs11767557). Here, CD33 is linked to Alzheimer disease.
