We screened LRRK2 mutations in exon 41 in 904 parkin-negative Parkinson's disease (PD) patients (868 probands) from 18 countries across 5 continents. We found three heterozygous missense (novel I2012T, G2019S, and I2020T) mutations in LRRK2 exon 41. We identified 11 (1.3%) among 868 PD probands, inc

Abstract
We present results of mutation screening of exons 31, 34, 35, 41, and 48 of LRRK2 in 205 Iranian Parkinson's disease patients. Sixteen percent of the cases were familial. Although age was not a factor in patient recruitment, the Iranian cohort was relatively young (average age at onset of disease: 48.9 years). A notably high male to female ratio (2.96:1) and earlier age at onset (by 2.9 years) in men were observed. A known diseaseβassociated variation, c.C4321T causing R1441C, and IVS31 + 3A > G, a variation that may be associated, were observed. Therefore, disregarding IVS31 + 3A > G, disease status in at least 0.5% of our young cohort and in 3.5% of the familial cases was associated with a mutation in the five exons of LRRK2 screened. Interestingly, the variation causing p.G2019S was not observed. Β© 2009 Movement Disorder Society

## Abstract The G2019S mutation in the __LRRK2__ gene is reportedly a common cause of familial Parkinson's disease (PD) and may also have a significant role in nonfamilial PD. The objective of this study was to assess mutation carrier frequency in PD patients from movement disorder clinics in the U
## Abstract The aim of the study was to evaluate the frequency and to perform phenotypic and genotypic characterization of familial Parkinsonism and early onset Parkinson's disease (EOPD) in a Brazilian movement disorder unit. We performed a standardized clinical assessment of patients followed by
