Genetic Evidence Supporting a Role for Brain Region Volume and Functional Network Alterations in Major Depression

open access: yesAdvanced Science, EarlyView.
Genome‐wide analyses indicate that reduced ventral diencephalon and thalamus volumes, along with decreased functional connectivity within the triple network (DMN/CEN/SN), are uniquely associated with the risk of major depression (MD) onset, compared to other similar severe psychiatric disorders.

Predicting the range of linkage disequilibrium [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
A generally accepted strategy in the mapping of a disease gene is to initially apply linkage analysis for an approximate estimate of the location of the trait gene and to subsequently make use of linkage disequilibrium (association) for a more accurate localization.

Inferring linkage disequilibrium from non-random samples

open access: yesBMC Genomics, 2010
Background Linkage disequilibrium (LD) plays a fundamental role in population genetics and in the current surge of studies to screen for subtle genetic variants affecting complex traits.

Similar patterns of genetic diversity and linkage disequilibrium in Western chimpanzees (Pan troglodytes verus) and humans indicate highly conserved mechanisms of MHC molecular evolution

open access: yesBMC Evolutionary Biology, 2020
Background Many species are threatened with extinction as their population sizes decrease with changing environments or face novel pathogenic threats.

Identification of Genetic Loci Associated with Quality Traits in Almond via Association Mapping. [PDF]

open access: yesPLoS ONE, 2015
To design an appropriate association study, we need to understand population structure and the structure of linkage disequilibrium within and among populations as well as in different regions of the genome in an organism.

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

open access: yesAdvanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

Decay of linkage disequilibrium within genes across HGDP-CEPH human samples: most population isolates do not show increased LD

open access: yesBMC Genomics, 2009
Background It is well known that the pattern of linkage disequilibrium varies between human populations, with remarkable geographical stratification.

Linkage Disequilibrium-Based Inference of Genome Homology and Chromosomal Rearrangements Between Species

open access: yesG3: Genes, Genomes, Genetics, 2020
The aim of this study was to analyze the genomic homology between cattle (Bos taurus) and buffaloes (Bubalus bubalis) and to propose a rearrangement of the buffalo genome through linkage disequilibrium analyses of buffalo SNP markers referenced in the ...

Effects of Overlapping Generations on Linkage Disequilibrium Estimates of Effective Population Size

open access: yesGenetics, 2014
Use of single-sample genetic methods to estimate effective population size has skyrocketed in recent years. Although the underlying models assume discrete generations, they are widely applied to age-structured species.

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.
