✓ Peer-reviewed alzhub usefulness score 67 out of 100. TREM2 and immune genetics

Topic: Brain proteins, microglia and lab models

A rare TREM2 missense mutation (rs75932628-T) was reported to confer a significant Alzheimer's disease (AD) risk. A recent study indicated no evidence of the involvement of this variant in Parkinson's disease (PD). Here, we used the genetic and expression data to reinvestigate the potential association between TREM2 and PD susceptibility.

Key findings

Why it matters

This meta-analysis found a significant association between the TREM2 rs75932628 variant and Parkinson's disease risk. It is about Parkinson's disease, not Alzheimer's, and does not report a treatment or cure.

Published in a peer-reviewed journal, and it is a meta-analysis pooling many studies. Scored zero for effect reported because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 64 of the 96 points we could judge it on, which is 67 out of 100.
