  "account": "Mouse gene knockout studies play a crucial role in understanding human gene function and disease mechanisms. However, bridging the gap between mouse and human phenotypes necessitates causal similarities between the two. A mouse model is considered transportable if gene perturbations that affect the mouse phenotype also influence the corresponding human phenotype of interest, maintaining consistent directionality. To evaluate the transportability of mouse models to human complex traits, researchers integrated laboratory mouse gene perturbation data from the International Mouse Phenotyping Consortium with predicted loss-of-function data from the UK Biobank within the GPAT framework. When GPAT was applied to 30 matched mouse-human phenotype pairs, evidence of transportability was observed for 12 mouse phenotypes, encompassing biochemical (e.g., total cholesterol), cellular (e.g., lymphocyte counts), and anthropometric (e.g., length/height) traits. In contrast, limited evidence for transportability was found for other traits such as fat mass and body mass index, particularly under murine experimental conditions. Additionally, some evidence suggested transportability of mouse glucose measurements to diabetes mellitus in humans. On average, genome-wide perturbation effects on matched phenotypes demonstrated a positive correlation between mice and humans (meta-analysis GPAT P = 2.3x10^-27). Nevertheless, the correlation's strength was generally modest and variable across phenotypes, with certain gene perturbations exhibiting opposing associations in both species. This study underscores how perturbation data can quantitatively validate experimental models for elucidating human disease aetiology and emphasizes the necessity for a diverse set of orthogonal model systems, including supplementary models and challenges to mouse knockout systems, to investigate the underlying mechanisms of human genetic associations.",
