A variance components factor model for genetic association studies: a Bayesian analysis.

open access: yes, 2010
Studies of gene-trait associations for complex diseases often involve multiple traits that may vary by genotype groups or patterns. Such traits are usually manifestations of lower-dimensional latent factors or disease syndromes.

HLA Class I or Class II and Disease Association: Catch the Difference if You Can [PDF]

open access: yes, 2017
The association of autoimmune diseases with HLA has been known for many decades. To date, however, the underlying mechanisms have not been fully understood. The recently introduced genome-wide association studies (GWAS) have suggested that several genes

Association of Rab37 gene polymorphism and delayed menarche: a report of 2 060 women

open access: yes陆军军医大学学报
Objective‍ ‍To explore the association between single nucleotide polymorphism (SNP) of Rab37 gene and the age at menarche(AAM). Methods‍ ‍A case-control study design was used to conduct an epidemiologic survey on 2 060 women in a community in Jurong City,

Disease‐Concordant Twins Empower Genetic Association Studies [PDF]

open access: yesAnnals of Human Genetics, 2016
SummaryGenome‐wide association studies with moderate sample sizes are underpowered, especially when testing SNP alleles with low allele counts, a situation that may lead to high frequency of false‐positive results and lack of replication in independent studies.

Evaluation of bi-directional causal association between periodontitis and benign prostatic hyperplasia: epidemiological studies and two-sample mendelian randomization analysis

open access: yesFrontiers in Genetics
Background: Periodontitis and benign prostatic hyperplasia (BPH) are all common chronic diseases with higher incidence in middle-aged and old men. Several studies have indicated a potential association between periodontitis and BPH, although the findings

Association of polymorphic variants of PTPN22, TNF and VDR genes in children with lupus nephritis: A study in Colombian family triads

open access: yesBiomédica: revista del Instituto Nacional de Salud, 2017
Introduction: Systemic lupus erythematosus is an autoimmune disease in which the severity varies according to race, sex and age of onset. This variation is also observed in the genetic markers associated with the disease, including PTPN22, VDR and TNF ...

Accurate modeling of confounding variation in eQTL studies leads to a great increase in power to detect trans-regulatory effects [PDF]

open access: yes, 2011
Expression quantitative trait loci (eQTL) studies are an integral tool to investigate the genetic component of gene expression variation. A major challenge in the analysis of such studies are hidden confounding factors, such as unobserved covariates or ...

Statistical significance in genetic association studies

open access: yesClinical and Investigative Medicine, 2010
Clinical & Investigative Medicine (CIM) is receiving an increasing number of reports of candidate-based association studies. The track record of such studies in the past has been poor: numerous genetic associations reported from candidate gene studies have not been replicated in later studies.

Pooled Association Tests for Rare Genetic Variants: A Review and Some New Results

open access: yes, 2014
In the search for genetic factors that are associated with complex heritable human traits, considerable attention is now being focused on rare variants that individually have small effects.
