This page contains information regarding the PGS Catalog Project.
A polygenic score (PGS) aggregates the effects of many genetic variants into a single number which predicts genetic predisposition for a phenotype. PGS are typically composed of hundreds-to-millions of genetic variants (usually SNPs) which are combined using a weighted sum of allele dosages multiplied their corresponding effect sizes, as estimated from a relevant genome-wide association study (GWAS).
PGS nomenclature is heterogeneous: they can also be referred to as genetic scores or genomic scores, and as polygenic risk scores (PRS) or genomic risk scores (GRS) if they predict a discrete phenotype, such as a disease.
The PGS Catalog is an open database of published polygenic scores (PGS). Each PGS in the Catalog is consistently annotated with relevant metadata; including scoring files (variants, effect alleles/weights), annotations of how the PGS was developed and applied, and evaluations of their predictive performance. See the PGS Catalog Data Description page for a complete description of the metadata captured for PGS, Samples, Performance Metrics, Traits, and Publications.
The Catalog is under active development, and a flagship publication is in preparation for early 2020. If you use the catalog before then we ask that you cite it as:

For a publication's data to be included in the PGS Catalog it must contain one of the following:
A complete description of the data captured for each PGS and publication can be found here.
In the pilot PGS Catalog (presented at ASHG 2019) we focused on curating PGS developed after 2010, and included well-studied scores for the following traits: coronary artery disease (CAD), diabetes (types 1 and 2), obesity / body mass index (BMI), breast cancer, prostate cancer and Alzheimer’s disease. The catalog however is not limited to these traits, and since then we have focused on broadening the coverage of traits and scores. Researchers are invited to submit their PGS and evaluations to us by e-mail for curation and inclusion in the PGS Catalog - we plan to provide a streamlined interface to submit these data in the future.
If you have a PGS or publication that meets the Catalog's eligibility requirements we invite you to submit your data by e-mail ( firstname.lastname@example.org). To ensure a speedy curation and inclusion into the catalog it would be helpful if you provide the following information about your study:
To submit a PGS to the catalog, provide feedback, or ask questions please contact the PGS Catalog team at email@example.com.
