(MAF ≥ 0.05) in YRI, ASN, and EUR, respectively. The Smokescreen array includes extensive custom content (350,209 markers), focusing on enhancing coverage of gene regions and pathways related to addiction (dependence, drug metabolism, and treatment response), and attributable disease (proliferative, psychiatric and pulmonary outcomes) in multiple populations. Consortia developed arrays have similar goals: to provide content of value to researchers studying related phenotypes and to provide data for large meta-analyses and replication studies.
