WebGWAS are used to identify whether common SNPs in the population are associated with disease. This can be done by undertaking a case:control study to see whether a specific SNP is more common in people with a specific condition, compared to those without the condition. Take our position 5 SNP above. The purple circles represent the “G ... WebGenome wide associate studies (GWAS) are a common method used in associating single nucleotide polymorphisms (SNPs) to a disease or trait under study. I don't work in this field and I'm always wondering how p-values are calculated for each SNP? How do I interpret say, the p-value of a SNP identified in GWAS is 1 ⋅ 10 − 8? Is it significant? p-value
