We report here that the most common variant associated with PD in several world-wide populations, the p.G2019S mutation in LRRK2, is not overrepresented in this Nigerian population of PD patients; similarly, sequence variants in PRKN, which represent a significant proportion of PRKN mutations underlying PD, are also not significantly present in the studied cohort. This evidence concerns the gene PRKN and Parkinson disease.
