Variant p.R47H of triggering receptor expressed on myeloid cells 2 (TREM2) has been associated with Parkinson's disease (PD). We screened this TREM2-variant in 821 PD patients including 261 demented PD patients (PDD) and in healthy controls (n = 919). Neither the entire PD nor the small PDD sample was associated with p.R47H.
Keywords: Association; Dementia; Non-motor symptoms; Parkinson's disease; TREM2.
