Polygenic Score (PGS) ID: PGS005340

Predicted Trait
Reported Trait Body mass index (BMI)
Mapped Trait(s) body mass index (EFO_0004340)
Additional Trait Information This score is optimized for South Asian ancestry. Ancestry-specific PRS is prioritized as they demonstarted higher predictive performance compared to European-derived. If no matching ancestry-specific PRS is available, the European PRS may be used as an alternative.

Score Details

Score Construction
PGS Name O_MetPRS_noUKB_SAS
Development Method
Name LDpred2
Parameters Proportion of causal variant(p= 0.0001, 0.00018, 0.00032, 0.001, 0.0018, 0.0032, 0.0056, 0.01, 0.018, 0.032, 0.056, 0.1, 0.18, 0.32, 0.56, 1), heritability scales(s = 0.7, 1, and 1.4), and whether a sparse LD matrix was applied(T,F). The final score was generated by linearly combining the multi-ancestry PGS from Smit RAJ et al. (Nat Med, 2025) in the UK Biobank South Asian testing population.

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.
