Colocalization results format

vas1_info

The colocalization data contains data that was acquired by running a colocalization analysis between FinnGen data and other datasets.

The colocalization results are tab-separated files. The results contain one source1-phenotype1-locus1 source2-phenotype2-locus2-pair per line. More information about data sources, phenotypes and loci can be found in the Colocalization in FinnGen page.

The results contains the following columns:

Column name
Column description

source1

Data source 1, always FinnGen

source2

Data source 2

pheno1

Phenotype 1

pheno2

Phenotype 2

pheno1_description

Description of phenotype 1

pheno2_description

Description of phenotype 2

quant1

Data quantification for phenotype 1. For eQTL Catalog data, this can be exon counts, gene counts, transcript usage, txrevise event usage. For other sources blank.

quant2

Data quantification for phenotype 1. For eQTL Catalog data, this can be exon counts, gene counts, transcript usage, txrevise event usage. For other sources blank.

tissue1

Tissue for phenotype 1 if applicable

tissue2

Tissue for phenotype 1 if applicable

locus_id1

Locus identifier of credible set of pheno1, locus_id = top SNP (max PIP). Formatted as CHROM_POS_REF_ALT

locus_id2

Locus identifier of credible set of pheno2, locus_id = top SNP (max PIP). Formatted as CHROM_POS_REF_ALT

chrom

Chromosome where the loci are

start

Start position of intersecting credible sets (in bp, on build hg38)

stop

End position of intersecting credible sets (in bp, on build hg38)

clpp

Colocalization posterior probability: sum_i(PIP1_i*PIP2_i). See Colocalization in FinnGen for more information

clpa

Colocalization posterior agreement: sum_i(min(PIP1_i,PIP2_i)). See Colocalization in FinnGen for more information

vars

Intersecting variants

len_cs1

Amount of variants in pheno1 credible set

len_cs2

Amount of variants in pheno2 credible set

len_inter

Amount of variants shared between credible set 1 and credible set 2

vars1_info

Information about variants in the credible set of phenotype 1. Each variant has its variant identifier, PIP, beta, and p-value. Variant fields are separated by comma, and variants are separated by semicolon.

vars2_info

Information about variants in the credible set of phenotype 2. Each variant has its variant identifier, PIP, beta, and p-value. Variant fields are separated by comma, and variants are separated by semicolon.

beta1

effect size of lead SNP in locus 1

beta2

effect size of lead SNP in locus 2

pval1

p-value of lead SNP in locus 1

pval2

p-value of lead SNP in locus 2
