LRRK2 variation and Parkinson's disease in African Americans.

ABSTRACT: The global impact of LRRK2 mutations is yet to be realized with a lack of studies in specific ethnic groups, including those of Asian and African descent. Herein, we investigated the frequency of common LRRK2 variants by complete exon sequencing in a series of publicly available African American Parkinson's disease patients. Our study identified three novel synonymous exonic variants and 13 known coding variations; however, there did not appear to be any frequent (>5%) pathogenic mutations. Given the ethnic-specific LRRK2 variation previously identified in PD further studies in under-represented populations are warranted.
