Abstract

In recent years, the molecular etiology of parkinsonism has yielded to genetic analysis.<sup>1</sup> Mutations in the gene leucine-rich repeat kinase 2 (<i>LRRK2</i>) have the highest genotypic and population attributable risk. Disparate penetrance estimates have been reported using a variety of statistical analyses, ethnic populations, and sample sizes.<sup>2</sup> We compared the age-associated cumulative incidence (penetrance) of <i>LRRK2</i> p.G2019S patients from Tunisia and Norway.
