✓ Peer-reviewed alzhub usefulness score 53 out of 100. Risk genes beyond APOE

Topic: Brain proteins, microglia and lab models

Background Low frequency coding variants in TREM2 are associated with Alzheimer disease (AD) risk and cerebrospinal fluid (CSF) TREM2 protein levels are different between AD cases and controls. Similarly, TREM2 risk variant carriers also exhibit differential CSF TREM2 levels. TREM2 has three different alternative transcripts, but most of the functional studies only model the longest transcript.

Key findings

Why it matters

This study analyzed TREM2 brain transcript-specific expression and alternative splicing in Alzheimer's disease cases, TREM2 mutation carriers and cognitively normal controls. It is a genetic and expression study and does not show that targeting TREM2 treats, cures or prevents Alzheimer's disease.
