Abstract

We conduct a genome-wide association study (GWAS) of educational attainment (EA) in a sample of ~3 million individuals and identify 3,952 approximately uncorrelated genome-wide-significant single-nucleotide polymorphisms (SNPs). A genome-wide polygenic predictor, or polygenic index (PGI), explains 12–16% of EA variance and contributes to risk prediction for ten diseases. Direct effects (i.e., controlling for parental PGIs) explain roughly half the PGI’s magnitude of association with EA and other phenotypes. The correlation between mate-pair PGIs is far too large to be consistent with phenotypic assortment alone, implying additional assortment on PGI-associated factors. In an additional GWAS of dominance deviations from the additive model, we identify no genome-wide-significant SNPs, and a separate X-chromosome additive GWAS identifies 57.

TL;DR

This GWAS meta-analysis of educational attainment in ~3.0 million individuals identified 3,952 approximately uncorrelated autosomal SNPs and a polygenic index explaining 12–16% of EA variance. It shows that the EA PGI’s predictive power partly reflects direct effects, predicts ten diseases, and has mate-pair PGI correlations too large to be explained by phenotypic assortment alone.

Key findings

  • The additive EduYears GWAS (N = 3,037,499) identified 3,952 lead SNPs (pairwise r² < 0.1, P < 5×10⁻⁸); the median SNP effect was 1.4 weeks more schooling per reference allele. The LDpred PGI explained 15.8% of EduYears variance in Add Health and 12.0% in HRS (sample-size-weighted mean 13.3%); an SBayesR PGI explained 17.0% and 12.9%, respectively (mean 14.3%).
  • The X-chromosome GWAS (N = 2,713,033) identified 57 lead SNPs, with X-chromosome SNP heritability of 0.4% and male-female genetic correlation rg = 0.94 (S.E. = 0.03). The dominance GWAS (N = 2,574,253) identified no genome-wide-significant SNPs; dominance SNP heritability was 0.00015 (S.E. = 0.00024, P = 0.54), and the inbreeding-depression estimate implied offspring of first cousins have ~1.0 fewer month of EA (P = 0.04).
  • The EA PGI significantly predicted all ten diseases examined; mean incremental R² was 0.63%, compared with 1.19% for disease-specific PGIs. For EA, the ratio of direct to population effect was 0.556 (S.E. = 0.020), implying 30.9% of the PGI’s R² was due to direct effects; corresponding ratios were 0.910 for height, 0.962 for BMI, and 0.824 for cognitive performance.
  • Mate-pair EA PGI correlation was 0.175 (S.E. = 0.020), versus 0.031 (S.E. = 0.004) predicted by phenotypic assortment; for height, observed 0.106 (S.E. = 0.020) versus predicted 0.087 (S.E. = 0.007). Residualizing EA PGI on EA reduced the mate-pair correlation by only 37%, to 0.110 (S.E. = 0.021); further adjustment for 40 PCs reduced it to 0.091 (S.E. = 0.021).

Methods

  • Meta-analysis of EduYears combined prior public results from 69 cohorts (N = 324,162, excluding UKB and 23andMe), new 23andMe results (N = 2,272,216), and new UKB results (N = 441,121), totaling N = 3,037,499, all in European genetic ancestries, with controls for sex, year of birth, their interaction, and genetic principal components; METAL sample-size-weighted meta-analysis and LD score intercept 1.663.
  • Separate X-chromosome meta-analysis (N = 2,713,033) and dominance-deviation GWAS meta-analysis (N = 2,574,253) were conducted; dominance analyses used adapted LD score regression and ldscdom for inbreeding depression.
  • Polygenic prediction used Add Health, HRS, and WLS holdout samples, with LDpred HapMap3 PGIs as main and SBayesR post hoc; disease prediction used UKB and Nagelkerke incremental R². Within-family analyses used ~53,000 individuals with genotyped siblings and ~3,500 with both parents genotyped from UKB, Generation Scotland, and the Swedish Twin Registry; assortative-mating analyses used 862 UKB and 1,603 Generation Scotland mate pairs.

Limitations

  • Stated: all main GWAS analyses were restricted to European genetic ancestries, and the PGI had much lower predictive power in African-genetic-ancestry samples (incremental R² 1.3% in HRS and 2.3% in Add Health; relative accuracies 11% and 15%). The paper also states the PGI cannot be used to meaningfully predict an individual’s EA, that dominance results do not rule out rare SNPs with substantial dominance effects, and that family samples lacked power for the ten diseases.
  • Evident: the dominance GWAS addresses common SNPs and found no genome-wide-significant dominance effects; family/direct-effect analyses are limited to ~53,000 siblings, ~3,500 parent-genotyped individuals, and 23 phenotypes.
  • Evident: assortative-mating analyses rely on UKB and Generation Scotland mate pairs and leave a substantial mate-pair PGI correlation unexplained after adjustment for EA, PCs, cognitive performance, and vocabulary.

    Any model of EA that requires substantial dominance to fit the data, restricts gene-environment correlations to zero, or assumes assortative mating is purely based on phenotype is likely to be misspecified.

    Any factor that contributes to explaining the mate-pair PGI correlation must be correlated with the EA PGI; therefore, these factors likely contribute to the EA PGI's predictive power for EA and other phenotypes.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-29.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-29.

Cited sources are checked by gpt-6-sol.

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.
