Abstract Details

Parkinson Disease Phenotype in Ashkenazi Jews with and without LRRK2 Mutations
Movement Disorders
S13 - (-)
004
Parkinson's disease (PD) phenotype of carriers of LRRK2 carriers is often similar to non-carriers.
The study included 456 AJ PD probands from three centers: Columbia University (n=141), Beth Israel (n=129), NY, and Tel-Aviv (n=186), Israel. Participants were either newly recruited (n=393; including 77 LRRK2 G2019S mutation carriers, 19.6%), or previously recruited (n=63). A total of 122 carriers were examined. Carriers of glucocerebrosidase mutations were excluded. Participants' phenotype was characterized by treating-physicians and self report questionnaires as well as the Montreal Cognitive Assessment (MoCA), the Unified Parkinson's Disease Rating Scale (UPDRS), the geriatric depression scale (GDS) and the non motor symptoms (NMS) questionnaire. Regression models were constructed to test the association between clinical and demographic features (predictor) and LRRK2 status (outcome).
Carriers and non carriers of LRRK2 G2019S were similar in age (67.5yrs versus 67.7yrs), gender distribution (59.7% versus 57.7% male), UPDRS-III (20.8 versus 19.5), MoCA (24.9 versus 24.8), GDS (5.7 versus 5.8) and NMS (8.4 versus 8.1) scores. However, mean age-at-onset (AAO) was lower among carriers (57.8yrs versus 61.4yrs, p=0.004), disease duration longer (9.4yrs versus 6.6yrs, p<0.001) and carriers' disease onset more often involved the legs (31.3% versus 10.7% p=0.001). In logistic models adjusted for age, disease-duration, gender and recruitment site, carriers were more likely to have lower extremity onset (p=0.003), persistent levodopa response for >5 years (p<0.001) and dyskinesia (p=0.041), as assessed by their treating clinicians. Performance on UPDRS, MoCA, GDS and NMS did not differ by mutation status in the adjusted model.
LRRK2 PD in AJ is characterized by earlier AAO and frequent lower extremity involvement at onset, persistent response to levodopa and dyskinesia.
