Score Details

Score Construction
PGS Name mono_p
Variants
Original Genome Build GRCh37
Number of Variants 583
Development Method
Name Regularized Regression (Elastic Net)
Parameters Variants included in the regression were selected according to their GWAS significance (p < 8.31e-9) and a subsequent conditional analysis (r2 threshold = 0.9); effect sizes of variants are estimated by regularized regression

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.
