Trascriptome-wide Association Study in UK Twins. Comparison of the results obtained in the transcriptome-wide association when the relatedness between subjects was evaluated using the family structures and when it was inferred from genome-wide SNPs by means of LDAK [12]. Left panel effect size estimates for the association between gene expression levels and BMI. Right panel estimated genetic (\(\sigma _{a}^{2}\), in blue) and environmental (\(\sigma _{e}^{2}\), in red) variances
