Abstract:
We developed and implemented software for the analysis of genome-wide association studies in the context of biological pathway enrichment and have here applied our algorithm to the study of Alzheimer disease (AD). Using genome-wide association data in a large French population, we observed a highly significant enrichment of genes involved in intracellular protein transmembrane transport, including several mitochondrial proteins and nucleoporins. An intriguing aspect of these findings is the implication that TOMM40, the channel-forming subunit of the translocase of the mitochondrial outer membrane complex, and a gene generally considered to be indiscernible from APOE because of linkage disequilibrium, may itself contribute to Alzheimer pathology. Results provide an indication that protein trafficking, in particular across the nuclear and mitochondrial membranes, may contribute to risk for AD.

Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...
