Objectives: To perform the largest PD genome-wide association study restricted to a single country. Methods: We performed a GWAS for both risk of PD and age at onset in 7,849 Spanish individuals. Further analyses included population-specific risk haplotype assessments, polygenic risk scoring through machine learning, Mendelian randomization of expression, and methylation data to gain insight into disease-associated loci, heritability estimates, genetic correlations, and burden analyses. Results: We identified a novel population-specific genome-wide association study signal at PARK2 associated with age at onset, which was likely dependent on the c.155delA mutation. We replicated four genome-wide independent signals associated with PD risk, including SNCA, LRRK2, KANSL1/MAPT, and HLA-DQB1. A significant trend for smaller risk haplotypes at known loci was found compared to similar studies of non-Spanish origin. Seventeen PD-related genes showed functional consequence by two-sample Mendelian randomization in expression and methylation data sets. Long runs of homozygosity at 28 known genes/loci were found to be enriched in cases versus controls. Conclusions: Our data demonstrate the utility of the Spanish risk haplotype substructure for future fine-mapping efforts, showing how leveraging unique and diverse population histories can benefit genetic studies of complex diseases. The present study points to PARK2 as a major hallmark of PD etiology in Spain.}, organization = {National Institutes of Health 1ZIA NS003154-03, Z01-AG000949-02, Z01-ES101986}, organization = {Department of Defense (award W81XWH-09-2-0128)}, organization = {Foundation for Parkinson’s Research}, organization = {ISCIII Grants PI 15/0878 (Fondos Feder), PI 15/01013}, organization = {Spanish Ministry of Economy and Competitiveness (PI14/01823, PI16/01575, PI18/01898, [SAF2006-10126 (2006-2009), SAF2010-22329-C02-01 (2010-2012), and SAF2013-47939-R (2013-2018)])}, organization = {Sociedad Andaluza de Neurología}, organization = {Jacques and Gloria Gossweiler Foundation}, organization = {Fundación Alicia Koplowitz}, organization = {Fundación Mutua Madrileña}, organization = {ISCIII16 FEDER}, organization = {ISCIII-FEDER}, organization = {Universidad de Sevilla}, organization = {ISCIII-Red de Biobancos PT13/0010/0056}, organization = {Junta de Andalucía (CVI-02526, CTS-7685), (PI-0437-2012, PI-0471-2013, PSI2014-57643)}, organization = {Andalusian Society of Neurology CTS-438}, publisher = {Wiley}, keywords = {Age at onset}, keywords = {Parkinson’s disease}, keywords = {Polygenic risk score}, keywords = {Risk haplotype}, keywords = {Spanish population}, title = {The Genetic Architecture of Parkinson Disease in Spain: Characterizing Population-Specific Risk, Differential Haplotype Structures, and Providing Etiologic Insight.}, doi = {10.1002/mds.27864}, author = {Bandres-Ciga, Sara and Sarah, Ahmed and Marya S., Sabir and Blauwendraat, Cornelis and Adarmes-Gómez, Astrid D and Bernal-Bernal, Inmaculada and Bonilla-Toribio, Marta and Buiza-Rueda, Dolores and Carrillo, Fátima and Carrión-Claro, Mario and Gómez Garre, Pilar and Jesús, Silvia and Labrador-Espinosa, Miguel A. and Macías, Daniel and Méndez-del-Barrio, Carlota and Periñán-Tocino, Teresa and Tejera-Parrado, Cristina and Vargas González, Laura and Diez-Fairen, Monica and Alvarez, Ignacio and Tartari, Juan Pablo and Buongiorno, Mariateresa and Aguilar, Miguel and Gorostidi, Ana and Bergareche, Jesús Alberto and Mondragon, Elisabet and Vinagre-Aragon, Ana and Croitoru, Ioana and Ruiz-Martínez, Javier and Dols-Icardo, Oriol and Kulisevsky, Jaime and Marín-Lahoz, Juan and Pagonabarraga, Javier and Pascual-Sedano, Berta and Ezquerra, Mario and Cámara, Ana and Compta, Yaroslau and Fernández, Manel and Fernández-Santiago, Rubén and Muñoz, Estaban and Tolosa, Eduard and Valldeoriola, Francesc and Gonzalez-Aramburu, Isabel and Sanchez Rodriguez, Antonio and Sierra, Maria and Menéndez-González, Manuel and Blazquez, Marta and García, Ciara and Suarez-San Martin, Esther and García-Ruiz, Pedro and Martínez-Castrillo, Juan Carlos and Vela-Desojo, Lydia and Ruz, Clara and Barrero Hernández, Francisco Javier and Escamilla-Sevilla, Francisco and Mínguez-Castellanos, Adolfo and Cerdan, Debora and Tabernero, Cesar and Gómez Heredia, Maria José and Pérez Errazquin, Francisco and Romero Acebal, Manuel and Feliz, Cici and Lopez-Sendon, Jose Luis and Mata, Marina and Martínez Torres, Irene and Kim, Jonggeol Jeffrey and Dalgard, Clifton L and Brooks, Janet and Saez- SaezAtienzar, Sara and Gibbs, J.
