Effect of ancestry and shared genetic architecture of serious mental illness on symptoms and cognition in an admixed Latin American population

Nelson B. Freimer, Esteban A. Lopera-Maya, Susan Service…·Carlos López-Jaramillo

The paper shows that European GWAS findings for serious mental illness and cognition are portable to an admixed Latin American population, associating genetic risk scores with multiple symptoms and cognitive traits.
