Defining The Role Of Rare Genetic Variants That Drive Risk And Pathogenesis Of Alzheimer’S Disease, Matthew James Rosene

Arts & Sciences Electronic Theses and Dissertations

Alzheimer’s disease (AD) is the leading cause of dementia and is pathologically defined by the aggregation of extracellular amyloid plaques and intracellular neurofibrillary tangles. Rare heritable mutations within the genes for amyloid precursor protein (APP) and presenilin 1 (PSEN1), and presenilin 2 (PSEN2) cause early onset AD and account for approximately 1% of AD cases. While the majority of AD cases are late-onset (LOAD), which is defined by a markedly more complex genetic architecture that is comprised of many genetic risk factors that influence AD through multiple cellular pathways. The advent of deep sequencing analyses have allowed for the identification …
