BCL9 and Alzheimer disease: Associated variants from two human GWASs overlapped with the LR risk locus; one associated variant from the human GWAS of AD7 is located ~14 kb from effect variant chr17:c, upstream of BCL9, and one AD-associated variant from the human multi-ancestry meta-GWAS6 is located in between effect variant chr17:h and chr17:i (Fig. 3).
