TDP-43 proteinopathy leads to progressive nuclear depletion, causing widespread alternative splicing defects at synapses. Despite highest original confidence (0.82), mechanistic critiques reveal causality gaps. ASO-based approach is Tier 3 with 10-12 year timeline.
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
