CHARGE Results

CHARGE Results in dbGaP

CHARGE Consortium working groups may release summary data from genome-wide meta analyses to allow the scientific community to examine associations of variants or loci of their interest for association with these traits. The files typically include p-values and direction of effect for millions of genotyped or imputed single nucleotide polymorphisms (SNPs). Some of these results are now available via dbGaP accession phs000930, where association results can be viewed in the Genome Browser and full summary statistics can be downloaded via authorized access. 

A further description is available in a Correspondence to Nature Genetics : 

Rapid evaluation of phenotypes, SNPs and results through the dbGaP CHARGE Summary Results site.

The list of available traits increases quarterly. A current list of available analyses can be found by browsing dbGaP. A sample of initial analysis results is listed below.

Other CHARGE Results

CHARGE Fatty Acids Working Group

Posted files from the CHARGE Fatty Acids Working Group are comprehensive meta-analysis results of GWAS of fatty acid levels, without any exclusion. The published reports typically excluded SNPs associated with fatty acids in a single cohort, and SNPs with minor allele frequency < 1%.

N-3 Fatty Acids Association Results

Association results of circulating levels of four n-3 fatty acids were available for up to 8,866 adults of European descent from 5 GWAS and combined using inverse-variance meta-analysis.

If these results are helpful to you, please cite:

Four files with association results for ALA (18:3n3), EPA (20:5n3), DPA (22:5n3) and DHA (22:6n3) can be downloaded.

Very Long-Chain Saturated Fatty Acids Association Results

Association results of circulating levels of three very long-chain saturated fatty acids were available for up to 10,129 adults of European descent from 7 GWAS and combined using a z score–based meta-analysis.

If these results are helpful to you, please cite:

Five files with association results for 20:0 (arachidic acid), 22:0 (behenic acid) and 24:0 (lignoceric acid) can be downloaded:

Please note that z-score-based meta-analyses do not provide estimates of the size of the associations. The direction of the associations is provided by the sign of the z-score.

Trans-Fatty Acids Association Results

Association results of circulating levels of 5 trans-fatty acids were available for up to 8,013 adults of European descent from 7 GWAS, and combined using fixed-effect meta-analysis.

If these results are helpful to you, please cite:

N-6 Fatty Acids Association Results

Association results of circulating levels of 5 n-6 fatty acids were available for up to 8631 adults of European descent from 5 GWAS, and combined using fixed-effect meta-analysis.
