Abstract

With the acknowledgement that the human genome is almost identical to each other, we may raise the question: what makes each individual distinct. Specifically, how that genetic information will be changed in the process of aging to shape the diverse disease susceptibility for different human populations? With the advancement of high-throughput sequencing technologies, scientists can utilize them to trace the somatic variants and investigate their functional relationships with our body. Recent studies have suggested a link between brain mosaicism and neurodegenerative diseases, particularly Alzheimer’s disease. Brain mosaicism describes the phenomenon where different populations of cells within the same brain have distinct genetic compositions. As a result, different cells within the same individual can have slightly different genetic makeups, which may contribute to individual differences in brain function and disease susceptibility. However, the underlying mechanism of how the mosaic pattern of the somatic variants are contributing the AD disease is still unveiled. This review will explore recent research on brain mosaicism, its potential role in aging and Alzheimer’s disease (AD), and the technologies enabling these discoveries.
