Abstract

Recent work has demonstrated that some functional categories of the genome contribute disproportionately to the heritability of complex diseases. Here we analyze a broad set of functional elements, including cell type-specific elements, to estimate their polygenic contributions to heritability in genome-wide association studies (GWAS) of 17 complex diseases and traits with an average sample size of 73,599. To enable this analysis, we introduce a new method, stratified LD score regression, for partitioning heritability from GWAS summary statistics while accounting for linked markers. This new method is computationally tractable at very large sample sizes and leverages genome-wide information. Our findings include a large enrichment of heritability in conserved regions across many traits, a very large immunological disease-specific enrichment of heritability in FANTOM5 enhancers and many cell type-specific enrichments, including significant enrichment of central nervous system cell types in the heritability of body mass index, age at menarche, educational attainment and smoking behavior.

  • For reliability of S-LDSC heritability estimates, two thresholds were applied to select GWAS based on recommendations from Finucane et al. and the Neale lab.

    “For reliability of S-LDSC heritability estimates, we apply two thresholds to select GWAS based on recommendations from Finucane et al.38 and the Neale lab38,55,79.”

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as Finucane et al.38

    In Results, 'Simulation results: power and lack of bias' (page unavailable), Finucane et al. say they selected traits with a total SNP-heritability z-score above 7 because that score indicated power. 'Analysis of 17 traits using the full baseline model' likewise states a cutoff of at least 7. Our copy supports this GWAS-selection criterion, but does not provide a second threshold or attribute one to the Neale lab. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Traits were included only if they had high-confidence SNP heritability estimates, defined as effective sample size >40,000, standard error <6 times expected based on GWAS sample size, sex bias <3:1, and no nonlinear ordinal coding of numeric values.

    “High confidence estimates of SNP heritability: traits with an effective sample size of greater than 40,000, a standard error of less than 6 times expected based on the GWAS sample size, sex bias less than 3:1, no nonlinear ordinal coding of numeric values”

    From Quantifying the contribution of Neanderthal introgression to the heritability of complex traits (2021) · cites this paper as Finucane et al.38

    The Results sections on the 17-trait analysis and simulation power say the authors selected traits with sufficient sample size, SNP heritability, and polygenicity, specifically requiring a total SNP-heritability z-score of at least 7. They do not give the claimed >40,000 effective-sample-size threshold, standard-error limit, sex-ratio limit, or ordinal-coding rule. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Traits were included only if they were significantly heritable, defined as heritability estimates with P < 1.28 × 10−12 (z > 7).

    “Significantly heritable traits: phenotypes that have heritability estimates with P < 1.28 × 10−12 (z > 7)”
  • Partitioned heritability analysis by functional annotation with 53 categories did not identify strong enrichment in any category after correction for multiple testing.

    “Partitioned heritability analysis by functional annotation with 53 categories14 did not identify strong enrichment in any category after correction for multiple testing (Supplementary Table 6), likely due to insufficient power.”
  • Partitioned heritability and LDSC-SEG analyses showed similar results for both EAS and EUR populations.

    “our partitioned heritability and LDSC-SEG analyses24,25 showed similar results for both populations.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
