To date, despite theirs being the largest minority group in the US (U.S. Census Bureau American Community Survey, 2017), only a handful of genomic studies studying the major PD genes (LRRK2, PARK2, PARK7, PINK1, and SNCA) have focused on PD patients of Hispanic ancestry (Deng et al., 2006; Alcalay et al., 2010; Marder et al., 2010; Saunders-Pullman et al., 2011; Gatto et al., 2013; Duque et al., 2015; Cornejo-Olivas et al., 2017). This evidence concerns the gene SNCA and Parkinson disease.
