Abstract

Genome-wide association studies (GWAS) have identified >250 loci for body mass index (BMI), implicating pathways related to neuronal biology. Most GWAS loci represent clusters of common, noncoding variants from which pinpointing causal genes remains challenging. Here we combined data from 718,734 individuals to discover rare and low-frequency (minor allele frequency (MAF) < 5%) coding variants associated with BMI. We identified 14 coding variants in 13 genes, of which 8 variants were in genes (ZBTB7B, ACHE, RAPGEF3, RAB21, ZFHX3, ENTPD6, ZFR2 and ZNF169) newly implicated in human obesity, 2 variants were in genes (MC4R and KSR2) previously observed to be mutated in extreme obesity and 2 variants were in GIPR. The effect sizes of rare variants are ~10 times larger than those of common variants, with the largest effect observed in carriers of an MC4R mutation introducing a stop codon (p.Tyr35Ter, MAF = 0.01%), who weighed ~7 kg more than non-carriers. Pathway analyses based on the variants associated with BMI confirm enrichment of neuronal genes and provide new evidence for adipocyte and energy expenditure biology, widening the potential of genetically supported therapeutic targets in obesity.

Figure 1
Figure 1. Effect sizes (y-axis) of the 14 BMI-associated R/LF coding variants by their minor allele frequency
Effect sizes are expressed in body weight (kg) per allele, assuming a SD of 4.5 kg and an average-sized person of 1.7m tall. Solid markers indicate that the minor allele is associated with higher BMI, and clear markers indicate that the minor allele is associated with lower BMI. Variants were identified in all-ancestry analyses (light blue diamonds), the European ancestry analyses (dark blue square) and women-only analyses (pink diamond). Effect sizes for previously identified GWAS loci are shown in navy blue diamonds. The dotted line represents 80% power, assuming α = 2×10−7 and N= 525,000 (discovery sample size).

Figure 2. Heatmap showing DEPICT gene set enrichment results for suggestive and significant rare and low-frequency coding SNVs
For any given square, the color indicates how strongly the corresponding gene (x-axis) is predicted to belong to the reconstituted gene set (y-axis), based on the gene’s Z-score for gene set inclusion in DEPICT’s reconstituted gene sets (red indicates a higher, blue a lower Z-score). To visually reduce redundancy and increase clarity, we chose one representative "meta-gene set" for each group of highly correlated gene sets based on affinity propagation clustering (Online Methods, Supplementary Note). Heatmap intensity and DEPICT P-values (Supplementary Table 17) correspond to the most significantly enriched gene set within the meta-gene set. Annotations for genes indicate (1) whether it has an OMIM annotation as underlying a monogenic obesity disorder (black/grey), (2) the MAF of the significant ExomeChip (EC) variant (blue), (3) whether the variant’s P-value reached array-wide significance (<2×10−7) or suggestive significance (<5×10−4) (purple), (4) whether the variant was novel, overlapping “relaxed” GWAS signals from Locke et al. (GWAS P<5×10−4), or overlapping “stringent” GWAS hits (GWAS P<5×10−8) (pink), and (5) whether the gene was included in the gene set enrichment analysis or excluded by filters (orange/brown) (Online Methods, Supplementary Note). Annotations for gene sets indicate if the meta-gene set was significant (green; FDR <0.01, <0.05, or not significant) in the DEPICT analysis of GWAS results. Here, two regions of particularly strong gene set membership are shown (see full heat map in Supplementary Figure 10a).
