Alternative splicing is a key mechanism by which genetic variation contributes to human phenotypic diversity and disease risk, yet its incorporation into large-scale genetic studies remains limited. Here we utilize blood RNA-seq from 4,732 European-ancestry individuals in the INTERVAL cohort to construct genetic scores for junction-based splicing phenotypes, 13,851 of which showed R2 > 0.01 in withheld individuals. These models were used to predict splicing in the UK Biobank White-British subset...
