数据描述

The Polygenic Score (PGS) Catalog is an open database maintained by EMBL-EBI that provides a repository for polygenic scores (PGS), including metadata necessary for their application and evaluation. It contains 5,011 PGS entries associated with 656 traits, such as breast cancer and BMI, supported by relevant publications and tools like pgsc_calc for score calculation. The Catalog offers comprehensive details on the derivation of each PGS, the genetic variants involved, allele dosages, effect sizes from genome-wide association studies (GWAS), and performance metrics. Users can access metadata and scoring files through bulk downloads, command-line utilities, or a REST API. The dataset aims to facilitate research by standardizing PGS annotation and supporting the development and application of polygenic risk scores for predicting genetic predisposition to traits or diseases.
