AbstractFrom its inception in 1980, advancement of research was one of the primary missions of the Alzheimer's Association (also known as Alzheimer's Disease and Related Disorders Association) in addition to leading in family caregiver support, better care, public education, and awareness. Over the past 30 years, the Association has grown and expanded its engagement with the scientific community. In the past 10 years, its research budget has more than doubled, greatly increasing the number of research grants funded and the number of strategic projects supported. The leadership and members of the Medical and Scientific Advisory Council recognized that the growth of the Alzheimer's Association and the expanded mission of Medical & Scientific Relations Division necessitated a change in the mission and charge of the external scientific advisory function to the Association.

Abstract Introduction Genetic loci for Alzheimer's disease (AD) have been identified in whites of European ancestry, but the genetic architecture of AD among other populations is less understood. Methods We conducted a transethnic genome‐wide association study (GWAS) for late‐onset AD in Stage 1 sample including whites of European Ancestry, African‐Americans, Japanese, and Israeli‐Arabs assembled by the Alzheimer's Disease Genetics Consortium. Suggestive results from Stage 1 from novel loci were followed up using summarized results in the International Genomics Alzheimer's Project GWAS dataset. Results Genome‐wide significant (GWS) associations in single‐nucleotide polymorphism (SNP)–based tests ( P < 5 × 10 −8 ) were identified for SNPs in PFDN1/HBEGF , USP6NL/ECHDC3 , and BZRAP1‐AS1 and for the interaction of the (apolipoprotein E) APOE ε4 allele with NFIC SNP. We also obtained GWS evidence ( P < 2.7 × 10 −6 ) for gene‐based association in the total sample with a novel locus, TPBG ( P = 1.8 × 10 −6 ). Discussion Our findings highlight the value of transethnic studies for identifying novel AD susceptibility loci.
