Polygenic Score (PGS) ID: PGS000157

Predicted Trait
Reported Trait Melanoma
Mapped Trait(s) melanoma (EFO_0000756)
Released in PGS: April 29, 2020

Score Details

Score Construction
PGS Name cGRS_Melanoma
Original Genome Build NR
Number of Variants 17
Development Method
Name Pruning + Thresholding
Parameters GWAS significant and r2 < 0.2. PGS levels were computed as product(dosage*weight/expected risk effect), where the expected risk effect for each variant was calculated based on the risk allele frequence (f) and risk allele weight (OR) as f^2*OR^2 + 2f(1-f)OR + (1-f)^2.

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.
