Using Cox proportional hazard models to evaluate the risk of parkinsonism among family members of PD subjects, having a daughter with PD compared with a son was associated with increased risk of parkinsonism in the parent (HR 2.59, p=0.014) as was having a child with a LRRK2 G2019S mutation (HR 3.19, p=0.003).
We have identified Family SK where Lrrk2 G2019S segregates with slowly progressive parkinsonism and the affected proband has tau-immunopositive neurofibrillary tangle pathology.
Although effective deep brain stimulation of the subthalamic nucleus (STN-DBS) is reported in G2019S leucine-rich repeat kinase 2 (LRRK2) parkinsonism, response to surgery in other LRRK2 mutations has not been previously reported.
A series of 106 patients with isolated or familial Parkinsonism underwent clinical evaluation and genetic testing for the LRRK2 G2019S mutation which was identified in 34/106 patients (32%).
The leucine-rich repeat kinase 2 (Lrrk2) G2385R substitution is associated with familial parkinsonism, late-, and early-onset Parkinson's disease in ethnic Chinese Taiwanese.
