Discovery of the day
A large-scale genome-wide association meta-analysis across seven harmonized cohorts (n=2,614 older adults) identified six genetic loci that influence limbic white matter microstructure in aging and Alzheimer’s disease, with heritability estimates ranging from 26% to 60%. Notably, a signal implicating the oligodendrocyte-enriched cell-adhesion gene CDH19, as well as loci near RORA, FAM107B, and KC6, showed expression in brain tissue associated with cognition and AD neuropathology, converging on insulin and immune biology pathways. For your work on blood-based proteomic biomarkers, these findings provide genetic anchor points that could enhance multimodal biomarker panels by linking imaging-defined white matter integrity to molecular pathways, enabling more precise stratification of disease activity and progression in Alzheimer’s disease.
