[PDF][PDF] Modeling linkage disequilibrium increases accuracy of polygenic risk scores

BJ Vilhjálmsson, J Yang, HK Finucane, A Gusev… - The american journal of …, 2015 - cell.com
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

V Segura, BJ Vilhjálmsson, A Platt, A Korte, Ü Seren… - Nature …, 2012 - nature.com
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

…, SH Lee, G Trynka, H Finucane, BJ Vilhjálmsson… - The American Journal of …, 2014 - cell.com
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

A Kong, G Thorleifsson, ML Frigge, BJ Vilhjalmsson… - Science, 2018 - science.org
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 …

Polygenic risk score, parental socioeconomic status, family history of psychiatric disorders, and the risk for schizophrenia: a Danish population-based study and meta …

E Agerbo, PF Sullivan, BJ Vilhjalmsson… - JAMA …, 2015 - jamanetwork.com
Importance Schizophrenia has a complex etiology influenced both by genetic and nongenetic
factors but disentangling these factors is difficult. Objective To estimate (1) how strongly …

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

A Gusev, G Bhatia, N Zaitlen, BJ Vilhjalmsson… - PLoS …, 2013 - journals.plos.org
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 …

Genome-wide association study of 107 phenotypes in Arabidopsis thaliana inbred lines

S Atwell, YS Huang, BJ Vilhjálmsson, G Willems… - Nature, 2010 - nature.com
Although pioneered by human geneticists as a potential solution to the challenging problem
of finding the genetic basis of common human diseases 1 , 2 , genome-wide association (…

[HTML][HTML] Genome-wide association study of placental weight identifies distinct and shared genetic influences between placental and fetal growth

…, H Ullum, M Vaarasmaki, BJ Vilhjalmsson… - Nature Genetics, 2023 - nature.com
A well-functioning placenta is essential for fetal and maternal health throughout pregnancy.
Using placental weight as a proxy for placental growth, we report genome-wide association …

Efficient Bayesian mixed-model analysis increases association power in large cohorts

PR Loh, G Tucker, BK Bulik-Sullivan, BJ Vilhjálmsson… - Nature …, 2015 - nature.com
Linear mixed models are a powerful statistical tool for identifying genetic associations and
avoiding confounding. However, existing methods are computationally intractable in large …
