title: Evaluation of LRRK2 G2019S penetrance: relevance for genetic counseling in Parkinson disease.
abstract: We report the results of a family-based study of LRRK2 G2019S penetrance in Parkinson disease. We studied 19 families identified through the analysis of unrelated consecutive patients. The cumulative incidence of the disease was 15% at 60 years, 21% at 70 years, and 32% at 80 years. This study provides accurate estimates of G2019S penetrance by minimizing the selection bias.
