WebSep 24, 2024 · Notably, all three SNPs showed the consistent direction of effect between the cross-trait GWAS meta-analyses and the component single trait GWAS’s (Table S3). Moreover, the SNP shared by MS-IBD and MS-CD (i.e. rs13428812) also showed the same direction of effect in both cross-trait meta-analyses (Table S3). The results suggest that … Websizes for trait Y 1 and Y 2,respectively;Ns is the number of overlapping samples; ρ is the phenotypic correlation between overlapping samples; and l(j,c) is the LD score of SNP j, defined as ljðÞ;c ≔∑ k∈c r2ðÞÞj;k [12]. The genetic covariance ρg is estimated by the slope obtained from a linear regression of β jγ on l(j,c). We can ...
