The PGS Catalog FTP allows for consistent access to the bulk downloads, and is indexed by Polygenic Score (PGS) ID to allow programmatic access to score level data. The following diagram illustrates the FTP structure:

Each scoring file (variant information, effect alleles/weights) is formatted to be a gzipped tab-delimited text file, labelled by its PGS Catalog Score ID (e.g. PGS000001.txt.gz

It also has been edited to have consistent column headings based on the following schema:
Column Header | Field Name | Field Requirement | Field Description |
---|---|---|---|
Variant Description: | |||
rsID | dbSNP Accession ID (rsID) | Optional | The SNP’s rs ID. This column also contains HLA alleles in the standard notation (e.g. HLA-DQA1*0102) that aren’t always provided with chromosomal positions. |
chr_name | Location - Chromosome | Required | Chromosome name/number associated with the variant |
chr_position | Location - Position within the Chromosome | Required | Chromosomal position associated with the variant |
effect_allele | Effect Allele | Required | The allele that's dosage is counted (e.g. {0, 1, 2}) and multiplied by the variant's weight (effect_weight) when calculating score. The effect allele is also known as the 'risk allele'. |
other_allele | Other allele(s) | Recommended | The other allele(s) at the loci |
locus_name | Locus Name | Optional | This is kept in for loci where the variant may be referenced by the gene (APOE e4). It is also common (usually in smaller PGS) to see the variants named according to the genes they impact. |
is_haplotype is_diplotype | FLAG: Haplotype or Diplotype | Optional | This is a TRUE/FALSE variable that flags whether the effect allele is a haplotype/diplotype rather than a single SNP. Constituent SNPs in the haplotype are semi-colon separated. |
imputation_method | Imputation Method | Optional | This described whether the variant was specifically called with a specific imputation or variant calling method. This is mostly kept to describe HLA-genotyping methods (e.g. flag SNP2HLA, HLA*IMP) that gives alleles that are not referenced by genomic position. |
variant_description | Variant Description | Optional | This field describes any extra information about the variant (e.g. how it is genotyped or scored) that cannot be captured by the other fields. |
inclusion_criteria | Score Inclusion Criteria | Optional | Explanation of when this variant gets included into the PGS (e.g. if it depends on the results from other variants). |
Weight Information: | |||
effect_weight | Variant Weight | Required | Value of the effect that is multiplied by the dosage of the effect allele (effect_allele) when calculating the score. Additional information on how the effect_weight was derived is in the weight_type field of the header, and score development method in the metadata downloads. |
is_interaction | FLAG: Interaction | Optional | This is a TRUE/FALSE variable that flags whether the weight should be multiplied with the dosage of more than one variant. Interactions are demarcated with a _x_ between entries for each of the variants present in the interaction. |
is_dominant | FLAG: Dominant Inheritance Model | Optional | This is a TRUE/FALSE variable that flags whether the weight should be added to the PGS sum if there is at least 1 copy of the effect allele (e.g. it is a dominant allele). |
is_recessive | FLAG: Recessive Inheritance Model | Optional | This is a TRUE/FALSE variable that flags whether the weight should be added to the PGS sum only if there are 2 copies of the effect allele (e.g. it is a recessive allele). |
dosage_0_weight | Effect weight with 0 copy of the effect allele | Optional | Weights that are specific to different dosages of the effect_allele (e.g. {0, 1, 2} copies) can also be reported when the the contribution of the variants to the score is not encoded as additive, dominant, or recessive. In this case three columns are added corresponding to which variant weight should be applied for each dosage, where the column name is formated as dosage_#_weight where the # sign indicates the number of effect_allele copies. |
dosage_1_weight | Effect weight with 1 copy of the effect allele | Optional | |
dosage_2_weight | Effect weight with 2 copies of the effect allele | Optional | |
Other information: | |||
OR HR | Odds Ratio [OR], Hazard Ratio [HR] | Optional | Author-reported effect sizes can be supplied to the Catalog. If no other effect_weight is given the weight is calculated using the log(OR) or log(HR). |
allelefrequency_effect | Effect Allele Frequency | Optional | Reported effect allele frequency, if the associated locus is a haplotype then haplotype frequency will be extracted. |
allelefrequency_effect_Ancestry | Population-specific effect allele frequency | Optional | Reported effect allele frequency in a specific population (described by the authors). |
