Principal components analysis corrects for stratification in genome-wide association studies
Population stratification—allele frequency differences between cases and controls due to systematic ancestry differences—can cause spurious associations in disease studies. We describe a method thatExpand

Population Structure and Eigenanalysis
Current methods for inferring population structure from genetic data do not provide formal significance tests for population differentiation. We discuss an approach to studying population structureExpand

Integrating common and rare genetic variation in diverse human populations
Despite great progress in identifying genetic variants that influence human disease, most inherited risk remains unexplained. A more complete understanding requires genome-wide studies that fullyExpand

Reconstructing Indian Population History
India has been underrepresented in genome-wide surveys of human variation. We analyse 25 diverse groups in India to provide strong evidence for two ancient populations, genetically divergent, thatExpand

De novo identification of repeat families in large genomes
TLDR
We develop a new method for de novo identification of repeat families via extension of consensus seeds; our method enables a rigorous definition of repeat boundaries, a key issue in repeat analysis. Expand

An Atlas of Genetic Correlations across Human Diseases and Traits
Identifying genetic correlations between complex traits and diseases can provide useful etiological insights and help prioritize likely causal relationships. The major challenges preventingExpand

LD Score regression distinguishes confounding from polygenicity in genome-wide association studies
Both polygenicity (many small genetic effects) and confounding biases, such as cryptic relatedness and population stratification, can yield an inflated distribution of test statistics in genome-wideExpand

Partitioning heritability by functional annotation using genome-wide association summary statistics
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,Expand

Sensitive Detection of Chromosomal Segments of Distinct Ancestry in Admixed Populations
Identifying the ancestry of chromosomal segments of distinct ancestry has a wide range of applications from disease mapping to learning about history. Most methods require the use of unlinkedExpand

New approaches to population stratification in genome-wide association studies
Genome-wide association (GWA) studies are an effective approach for identifying genetic variants associated with disease risk. GWA studies can be confounded by population stratification — systematicExpand
