Many genetic variants identified in genome-wide association studies (GWAS) are associated with multiple, sometimes seemingly unrelated, traits. (Author/PN) Multi-trait analysis has also been found to substantially increase prediction accuracy when some traits are observed in all individuals but the trait of interest is not observed in the individuals in the test set (Pszczola et al. 2020 Apr 15;46(5):1182-90. doi: 10.1093/schbul/sbaa053. [Epub ahead of print] Publisher Correction: Multi-trait analysis of genome-wide association summary statistics using MTAG. Multi-trait (MT) analysis revealed thirteen QTLs on nine chromosomes, significantly associated with resistance. 1. However, what is lacking are more powerful statistical models that can exploit the correlation between traits to improve prediction accuracy in the context of genomic selection (GS).

Nat Genet. Multi-trait meta-analysis chi-squared statistic. It was developed in 1959 by Campbell and Fiske (Campbell, D. and Fiske, D. (1959). We proposed a multi-trait association analysis method based on multivariate mixed linear model including additive, dominance, epistasis effects of QTS and their interaction effects with environments. We do not retain these email addresses. Phenotypic variation explained by all significant QTLs for KB, TS, Yr, Lr diseases were 57%, 55%, 38% and 22%, respectively. Multi-trait analyses, such as polygenic risk scores, offer insights into shared and distinct aetiology among different phenotypes, such as ADHD, autism, schizophrenia, eating disorders and obesity. Enter multiple addresses on separate lines or separate them with commas. In comparison, the competing methods either had a suspicious genomic inflation factor or identified much fewer risk loci.
