Abstract

Alzheimer's disease (AD) is a clinically heterogeneous neurodegenerative disease with a strong genetic component. Several genes have been associated with AD risk for nearly 20 years. However, it was not until the recent technological advances that allow for the analysis of millions of polymorphisms in thousands of subjects that we have been able to advance our understanding of the genetic complexity of AD susceptibility. Genome-wide association studies and whole-exome and whole-genome sequencing have revealed more than 20 loci associated with AD risk. These studies have provided insights into the molecular pathways that are altered in AD pathogenesis, which have, in turn, provided insight into novel therapeutic targets.

Figure 1. Cell-type expression of Alzheimer’s disease risk genes may influence AD pathogenesis
The major cell-types present in the brain are depicted. Genes are listed in the cell-type in which they are most highly expressed (Ben Barres, personal communication). GWAS loci that contain multiple genes were excluded from this figure, as it remains unclear which gene is responsible for the signal (CR1, BIN1, PICALM, HLA, SLC24A4, DSG2, ZCWPW1, CELF1, FERMT2, CASS4).
