What molecular mechanisms underlie the localized genetic correlations between sarcopenia and AD at specific genomic regions?

OPEN

The study identifies three specific genomic regions with local genetic correlations despite no genome-wide correlation, but the mechanistic basis for this regional specificity remains unexplained. Understanding these mechanisms could reveal novel therapeutic targets for both conditions. Gap type: unexplained_observation Source paper: Uncovering polygenic and local genetic overlap between sarcopenia and Alzheimer's disease. (2026, J Alzheimers Dis, PMID:41940827)
