description: Cross-ancestry atlas of gene, isoform, and splicing regulation in the developing human brain

This repository contains summary statistics for gene, isoform, and splicing quantitative trait loci (cis-xQTLs) in the developing human brain across 672 unique samples from 4 to 39 postconception weeks spanning European (EUR), African-American (AFR), and Latino/admixed American (AMR) ancestries.

eQTLs

cis-eQTL Summary Statistics: All Samples combined





cis-eQTLs from nominal pass and permutation-based analysis (both FDR correcte) using 90 hidden covariates




see FastQTL and QTLtools papers & documentation for further details







devBrain_eQTL_ALL_nominal_90HCP_FDR_0.05.txt.gz





pid = ID of the tested molecular phenotype (in this particular case, the gene I)




sdi = ID of the tested variant (in this case a SN)




dist= Distance between the variant and the phenotype in bp




npval = The nominal p-value of association slope = The slope associated with the nominal p-value of association




fdr = fdr-corrected p-value






devBrain_eQTL_ALL_permutation_90HC_FDR_0.05.txt.gz





pid=ID of the tested molecular phenotype (in this particular case, the gene I)




nvar=Number of variants tested in cis for this phenotype




shape1=MLE of the shape1 parameter of the Beta distribution




shape2=MLE of the shape2 parameter of the Beta distribution




dummy=Dummy variable




sid=ID of the best variant found for this molecular phenotypes (i.e. with the smallest p-valu)




dist=Distance between the molecular phenotype - variant pair




npval=The nominal p-value of association that quantifies how significant from 0, the regression coefficient is




slope=The slope associated with the nominal p-value of association




ppval=A first permutation p-value directly obtained from the permutations with the direct method. This is basically a corrected version of the nominal p-value that accounts for the fact that multiple variants are tested per molecular phenotype.




bpval=A second permutation p-value obtained via beta approximation. We advice to use this one in any downstream analysis.




qval=fdr-corrected bpval




pval_nominal_threshold=npval corresponding to qval = 0.05
