Methylation QTLs in the developing brain and their enrichment in schizophrenia risk loci


We characterized DNA methylation quantitative trait loci (mQTLs) in a large collection (n = 166) of human fetal brain samples spanning 56–166 d post-conception, identifying >16,000 fetal brain mQTLs. Fetal brain mQTLs were primarily cis-acting, enriched in regulatory chromatin domains and transcription factor binding sites, and showed substantial overlap with genetic variants that were also associated with gene expression in the brain. Using tissue from three distinct regions of the adult brain (prefrontal cortex, striatum and cerebellum), we found that most fetal brain mQTLs were developmentally stable, although a subset was characterized by fetal-specific effects. Fetal brain mQTLs were enriched amongst risk loci identified in a recent large-scale genome-wide association study (GWAS) of schizophrenia, a severe psychiatric disorder with a hypothesized neurodevelopmental component. Finally, we found that mQTLs can be used to refine GWAS loci through the identification of discrete sites of variable fetal brain methylation associated with schizophrenia risk variants.

Figure 1: mQTLs in the developing human brain are predominantly cis-acting with effect size related to distance, although notable trans-effects are also present.
Figure 2: Despite a highly significant overall correlation of individual mQTL effects between fetal brain and adult brain regions, a subset of loci are characterized by fetal-specific mQTLs.
Figure 3: mQTL mapping can localize putative causal loci associated with disease.
Figure 4: Fetal mQTLs in schizophrenia-associated regions have larger effects on DNA methylation during neurodevelopment than the in adult brain.

Supplementary Figure 1 The distribution of effect sizes across all Bonferroni significant fetal brain mQTLs.

Shown is the DNA methylation difference (% DNA methylation) associated with each minor allele for all fetal brain mQTLs, cis-acting mQTLs, and trans-acting mQTLs. The average effect size for trans-mQTLs is significantly lower than that observed for cis-mQTLs (two-sided Wilcoxon rank sum test, P = 6.74x10−7).

Source data

Supplementary Figure 2 Frequency distribution of mQTL SNPs and associated DNA methylation sites.

A) mQTL SNPs are associated with DNA methylation at relatively few sites, but B) genetically-mediated DNA methylation sites are often associated with several mQTL SNPs.

Source data

Supplementary Figure 3 The statistical significance of association between genotype and DNA methylation is related to the distance between the Illumina 450K array probe and mQTL SNP.

Shown is the relationship between mQTL significance (–log10 P-value) and distance between the DNA methylation site and genetic variant in fetal brain samples.

Source data

Supplementary Figure 4 There is a highly-significant correlation of individual mQTL effects between fetal brain and each of the individual adult brain regions.

Shown are scatterplots showing the relationship in effect size (% DNA methylation change per allele) for all fetal brain mQTLs between fetal brain and a) PFC (r = 0.911, P < 2.2x10−16), b) STR (r = 0.899, P < 2.2x10−16) and c) CER (r = 0.835, P < 2.2x10−16).

Source data

Supplementary Figure 5 The correlation of mQTL effect sizes (% DNA methylation change per allele) between fetal brain and adult brain is stronger for replicating variants (left) than non-replicating variants (right).

Of note, fetal brain mQTLs that do not replicate in adult brain are characterized by significantly lower effect sizes across all brain regions (Supplementary Fig. 6).

Source data

Supplementary Figure 6 Fetal brain mQTLs that do not replicate in adult brain are characterized by significantly smaller effect sizes across all brain regions, including the initial fetal brain discovery sample (P = 3.18×10−141).

Supplementary Figure 7 SNPs associated with DNA methylation are more significantly associated with gene expression than non-mQTL variants.

Supplementary Figure 8 The overlap between independent fetal brain mQTL signals with the sentinelized subsignals from a brain eQTL dataset.

Histogram of overlap between simulated mQTL SNPs set (n = 1,000,000 simulations, matched for allele frequency) with the sentinelized eQTL set published by Ramasamy et al.. The vertical red line represents the true overlap, which is greater than any of the simulations (fold change = 4.23, P < 1.00x10−6 after 1 million simulations).

Supplementary Figure 9 Fetal brain mQTLs ar1e significantly enriched for schizophrenia genetic risk variants.

Different significance thresholds (represented by different colored bars) were used to classify SNP associations from a recent large GWAS analysis of schizophrenia1. There is an enrichment of schizophrenia-associated variants amongst fetal brain mQTLs at all tested GWAS significance thresholds. Shown is the enrichment fold-change with 95% confidence intervals based on 1 million simulated SNP-sets. See also Table 1.

Supplementary Figure 10 Boxplot of mQTL effects observed for rs2535627, an index SNP from the recent schizophrenia GWAS.

Shown are boxplots demonstrating the relationship between genotype and DNA methylation for rs2535627 and cg11645453. There is a significant association in the fetal brain (P = 3.05x10−13) but none of the adult brain regions tested.

Source data

Supplementary Figure 11 Boxplot of mQTL effect observed for rs4648845, an index SNP from a recent schizophrenia GWAS.

This boxplot demonstrates the relationship between genotype and DNA methylation for rs4648845 and cg02275930 in the fetal brain (P = 4.54x10−15). This mQTL was not tested in the adult brain regions because of the low minor allele frequency of rs4648845.

Source data

Supplementary Figure 12 mQTLs identified using imputed genetic data reflected the non-imputed dataset in terms of genomic distribution and observed effect sizes.

A) The genomic distribution of all imputed mQTLs in fetal brain, where the position on the x-axis indicates the location of Illumina 450K HumanMethylation array probes and the position on the y-axis indicates the location of all imputed SNPs. The color of the point corresponds to the difference in DNA methylation per allele, with the largest effects plotted in dark red. A clear positive diagonal can be observed demonstrating that the majority of mQTLs in fetal brain are associated with genotype in cis, reflecting the distribution shown in Fig. 1a. B) The distribution of effect sizes across all imputed fetal brain mQTLs. The distribution is similar to that for the non-imputed dataset (Supplementary Fig. 1).

Source data

Supplementary Figure 13 Effect sizes at fetal brain mQTLs identified in this study are highly correlated with those identified in an independent study of cortical mQTLs across development.

Effect sizes at mQTLs identified in this study (Hannon et al., X-axis) are highly correlated with those reported in a companion study (Jaffe et al., Y-axis). Each point represents a cis-mQTL identified in the current fetal brain dataset using the thresholds used by Jaffe et al [Nature Neuroscience, in press] (<20kb distance between SNP and DNA methylation site, FDR < 0.1).

Given that the causal variant at these loci is yet to be established, this list was extended to include additional variants in strong LD (r2 < 0.8 based on 1000 Genomes European populations) with these 125 autosomal index variants. For this list of 'likely causal variants', all Bonferroni significant fetal brain mQTLs were identified.

Genomic loci with evidence for association with both schizophrenia and DNA methylation. Co-localization analysis was performed using the publically available summary statistics from the PGC schizophrenia GWAS and imputed mQTLs generated in this study. This table contains the 306 pairs where the association for schizophrenia and a DNA methylation site overlap the same genomic region. This includes instances where either the same causal variant is associated with both phenotypes or there are separate signals for each disorder. The posterior probabilities for each hypothesis are reported (see Online Methods for details). (XLSX 98 kb)
