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 …

Genetic variance estimation with imputed variants finds negligible missing heritability for human height and body mass index
We propose a method (GREML-LDMS) to estimate heritability for human complex traits in
unrelated individuals using whole-genome sequencing data. We demonstrate using …

Contrasting genetic architectures of schizophrenia and other complex diseases using fast variance-components analysis
Heritability analyses of genome-wide association study (GWAS) cohorts have yielded
important insights into complex disease architecture, and increasing sample sizes hold the …

Efficient set tests for the genetic analysis of correlated traits
Set tests are a powerful approach for genome-wide association testing between groups of
genetic variants and quantitative traits. We describe mtSet (http://github. com/PMBio/limix), a …

Strategies for imputing and analyzing rare variants in association studies
TJ Hoffmann, JS Witte - Trends in Genetics, 2015 - cell.com
Rare genetic variants may be responsible for a significant amount of the uncharacterized
genetic risk underlying many diseases. An efficient approach to characterizing the disease …

Mixed model with correction for case-control ascertainment increases association power
We introduce a liability-threshold mixed linear model (LTMLM) association statistic for case-
control studies and show that it has a well-controlled false-positive rate and more power …

A new tool called DISSECT for analysing large genomic data sets using a Big Data approach
Large-scale genetic and genomic data are increasingly available and the major bottleneck
in their analysis is a lack of sufficiently scalable computational tools. To address this problem …
