In our simulations, we showed that pseudovalidation often resulted in prediction accuracy that is comparable to using a dataset with validation phenotype and was clearly superior to the conservative option of setting the tuning parameter of lassosum to its lowest value.

Figure S3 Examining the impact of the size of the reference panel in the prediction accuracy of lassosum. A polygenic score (PGS) or polygenic risk score (PRS) is an estimate of an individual's genetic liability to a trait or disease, calculated according to their genotype profile and relevant genome-wide association study (GWAS) data.

Accurate and Scalable Construction of Polygenic Scores in Large Biobank Data Sets. Figure S6 Computation time for running lassosum with different values of s vs LDpred in the a large simulated dataset with n=200,000 under different clumping scenarios.
Among a range of applications, PRS are exploited to assess shared aetiology between phenotypes, to evaluate the predictive power of genetic data for use in clinical settings, and as part of experimental studies in which, for example, experiments are performed on individuals, or their … The emerging landscape of health research based on biobanks linked to electronic health records: Existing resources, statistical challenges, and potential opportunities. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Only 3.8% of studies were among cohorts of African, Hispanic, or Indigenous peoples. We analyze the first decade of polygenic scoring studies (2008–2017, inclusive), and find that 67% of studies included exclusively European ancestry participants and another 19% included only East Asian ancestry participants. Meta-analysis of genome-wide association study identifies FBN2 as a novel locus associated with systemic lupus erythematosus in Thai population.
