WebTherefore, due to feasibility, simplicity, and interpretability, it might be best to perform regression on every single SNP. Now since we are running GWAS in an SNP-by-SNP fashion, there are a lot of work that needs to be done after GWAS in order to find the true causal SNP. Many fine-mapping methods have been developed to tackle this problem.
