Score Details

Score Construction
PGS Name TNBC_PRS25
Development Method
Name Genome-wide significant SNPs
Parameters After removal of variants with MAF < 0.01, an imputation quality score r2 of < 0.8, small INDELs, and the C/G or A/T SNPs due to strand ambiguity，SNPs with P<5×10-8 were included. The SNPs were clumped using r2<0.1, and the 1000 Genomes Phase 3 EUR data as the LD reference.
Variants
Original Genome Build GRCh37
Number of Variants 25

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.
