Abstract
Background
Α number of genetic variants are considered to confer susceptibility to Parkinson’s disease (PD). Rs75392628 (R47H), a rare variant of TREM2 gene, has been linked to PD, although its role on PD remains conflicting.
Objective
Detection of a possible contribution of rs75392628 variant of TREM2 gene to PD risk.
Methods
A total of 358 PD patients and 358 healthy controls genotyped for rs75392628. In addition, a meta-analysis was performed by merging our results with those from previous studies.
Results
The rare variant of rs75932628 (47H) of TREM2 gene was not detected on cohort. Meta-analysis of a total of 9271 PD cases and 9777 controls across 14 independent PD data sets from 9 studies, including the present study, did not show any statistically significant effect of rs75392628 on PD risk (ORFE:1.54 95% CI:0.87-2.73. ORRE: 1.54, 95%CI: 0.71-3.32).
Conclusions
Rs75392628 TREM2 variant is rather unlikely to be a major genetic risk contributor of PD.
