Mapping genomic loci implicates genes and synaptic biology in schizophrenia

…, T Kam-Thong, Y Kamatani, S Karachanak-Yankova… - Nature, 2022 - nature.com
Schizophrenia has a heritability of 60–80% 1 , much of which is attributable to common risk
alleles. Here, in a two-stage genome-wide association study of up to 76,755 individuals with …

Ancient human genomes suggest three ancestral populations for present-day Europeans

…, U Hodoglugil, AR Jha, S Karachanak-Yankova… - Nature, 2014 - nature.com
We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old
hunter-gatherers from Luxembourg and Sweden. We analysed these and other …

The Simons genome diversity project: 300 genomes from 142 diverse populations

…, E Balanovska, O Balanovsky, S Karachanak-Yankova… - Nature, 2016 - nature.com
Here we report the Simons Genome Diversity Project data set: high quality genomes from 300
individuals from 142 diverse populations. These genomes include at least 5.8 million base …

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

…, L Kalaydjieva, S Karachanak-Yankova… - 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 …

[PDF][PDF] Partitioning heritability of regulatory and cell-type-specific variants across 11 common diseases

…, L Kalaydjieva, S Karachanak-Yankova… - 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 …

Global diversity, population stratification, and selection of human copy-number variation

…, IG Romero, AR Jha, S Karachanak-Yankova… - Science, 2015 - science.org
INTRODUCTION Most studies of human genetic variation have focused on single-nucleotide
variants (SNVs). However, copy-number variants (CNVs) affect more base pairs of DNA …

A comparison of ten polygenic score methods for psychiatric disorders applied across multiple cohorts

…, RS Kahn, L Kalaydjieva, S Karachanak-Yankova… - Biological …, 2021 - Elsevier
Background Polygenic scores (PGSs), which assess the genetic risk of individuals for a disease,
are calculated as a weighted count of risk alleles identified in genome-wide association …

[PDF][PDF] Estimation of genetic correlation via linkage disequilibrium score regression and genomic restricted maximum likelihood

…, L Kalaydjieva, S Karachanak-Yankova… - The American Journal of …, 2018 - cell.com
Genetic correlation is a key population parameter that describes the shared genetic architecture
of complex traits and diseases. It can be estimated by current state-of-art methods, ie, …

Sex-dependent shared and nonshared genetic architecture across mood and psychotic disorders

…, RS Kahn, L Kalaydjieva, S Karachanak-Yankova… - Biological …, 2022 - Elsevier
Background Sex differences in incidence and/or presentation of schizophrenia (SCZ), major
depressive disorder (MDD), and bipolar disorder (BIP) are pervasive. Previous evidence for …

[PDF][PDF] The role of recent admixture in forming the contemporary West Eurasian genomic landscape

…, C Hayward, D Toncheva, S Karachanak-Yankova… - Current biology, 2015 - cell.com
Over the past few years, studies of DNA isolated from human fossils and archaeological
remains have generated considerable novel insight into the history of our species. Several …
