Polygenic Score (PGS) ID: PGS012521

Predicted Trait
Reported Trait Obstructive sleep apnea (adjusted for BMI)
Mapped Trait(s) obstructive sleep apnea syndrome (MONDO_0007147)
Additional Trait Information Binary sleep disorder outcome representing obstructive sleep apnea (OSA). Summary statistics used for polygenic score development were obtained from a multi-ethnic genome-wide association study conducted in the Million Veteran Program (PMID: 36989840). In this GWAS model, body mass index (BMI) was included as a covariate.

Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.
