To evaluate the frequency of the LRRK2 G2019S mutation in Italy, we tested 1,072 probands with Parkinson's disease (PD; 822 sporadic and 250 familial): 20 patients (1.9%) carried the G2019S mutation, 11 patients (1.3%) were sporadic, and 9 (4.3%) had a positive family history.

## Abstract The frequency and penetrance of the LRRK2 G2019S mutation varies considerably in different Parkinson disease (PD) populations. This information is essential both for clinical purposes and genetic counseling. The objective of this study was to estimate the prevalence and penetrance of th
genes and who were found to be negative. 1 In this group of 122 patients, we identified 5 patients with an FMR1 premutation and in 4 of them a definite diagnosis of fragile Xassociated tremor/ataxia syndrome (FXTAS) could be made, based on the proposed diagnostic criteria for FXTAS. We proposed base
