WebMar 22, 2024 · Genome-wide association studies (GWAS) help scientists identify genes associated with a particular disease (or another trait). This method studies the entire set … WebUnivariate LDSC intercepts close to 1 indicate that the GWAS calculation appropriately controlled for population stratification. When the LDSC intercept is much larger than 1.0, stratification is indicated because the expected value for SNPs with no effect under the null hypothesis is still association signal.
