{"product_id":"2940156912056","title":"Genome-wide association study","description":"In genetic epidemiology, a genome-wide association study (GWA study, or GWAS), also known as whole genome association study (WGA study, or WGAS), is an examination of many common genetic variants in different individuals to see if any variant is associated with a trait. GWASs typically focus on associations between single-nucleotide polymorphisms (SNPs) and traits like major diseases. These studies compare the DNA of participants having varying phenotypes for a particular trait or disease.","brand":"Charles Hunter","offers":[{"title":"Default Title","offer_id":47083618664688,"sku":"2940156912056","price":1.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940156912056_p0.jpg?v=1764089900","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940156912056","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
