[PDF][PDF] Modeling linkage disequilibrium increases accuracy of polygenic risk scores
Polygenic risk scores have shown great promise in predicting complex disease risk and will
become more accurate as training sample sizes increase. The standard approach for …

An efficient multi-locus mixed-model approach for genome-wide association studies in structured populations
Population structure causes genome-wide linkage disequilibrium between unlinked loci,
leading to statistical confounding in genome-wide association studies. Mixed models have …

[PDF][PDF] Partitioning heritability of regulatory and cell-type-specific variants across 11 common diseases
Regulatory and coding variants are known to be enriched with associations identified by
genome-wide association studies (GWASs) of complex disease, but their contributions to trait …

The nature of nurture: Effects of parental genotypes
Sequence variants in the parental genomes that are not transmitted to a child (the proband)
are often ignored in genetic studies. Here we show that nontransmitted alleles can affect a …

The nature of confounding in genome-wide association studies
BJ Vilhjálmsson, M Nordborg - Nature Reviews Genetics, 2013 - nature.com
The authors argue that population structure per se is not a problem in genome-wide association
studies — the true sources are the environment and the genetic background, and the …

[HTML][HTML] Quantifying missing heritability at known GWAS loci
Recent work has shown that much of the missing heritability of complex traits can be
resolved by estimates of heritability explained by all genotyped SNPs. However, it is currently …
