Non-coding variation in dementias: mechanisms, insights, and challenges.

Dementia encompasses many neurodegenerative disorders. While some causal coding variants are known, most GWAS variants are in non-coding regions of the genome, making understanding functional impacts challenging. This review explores the role of non-coding variation in dementia, covering methods to identify enhancers and their target genes, prioritize GWAS variants, and validate the functional effects of variation, providing a comprehensive framework for investigating non-coding variation and its implications in dementia research.
