With the discovery of massive numbers of genetic markers and the development of better tools for genotyping, association studies will inevitably proliferate and now is the time to consider critically the design of such studies to avoid the mistakes of the past and to maximize their potential to identify new components of disease.Abstract:
Assessing the association between DNA variants and disease has been used widely to identify regions of the genome and candidate genes that contribute to disease. However, there are numerous examples of associations that cannot be replicated, which has led to skepticism about the utility of the approach for common conditions. With the discovery of massive numbers of genetic markers and the development of better tools for genotyping, association studies will inevitably proliferate. Now is the time to consider critically the design of such studies, to avoid the mistakes of the past and to maximize their potential to identify new components of disease.read more

Effects of ethnicity on the distribution of clinically relevant endothelial nitric oxide variants.
TL;DR: The marked interethnic differences that are found in the distribution of eNOS variants, in the estimated haplotype frequency, and in the association between variants may help to understand how the combination of these genetic variants may influence cardiovascular diseases.

The genetics of NAFLD.
TL;DR: The current status of the field is described, discussing specific genetic and epigenetic modifiers, including the mechanisms through which genes identified by genome-wide association studies, including PNPLA3, influence disease progression.

TL;DR: The genetic data suggest a recessive model of inheritance, and ex vivo lipopolysaccharide-stimulated whole-blood TNF production to be higher in healthy TNF(-857C) homozygotes, and it is shown the transcription factor OCT1 binds TNF (-857T) but not TNF(8 57C), and interacts in vitro and in vivo with the pro-inflammatory NF(-kappa)B transcription factor p65 subunit at an adjacent binding site

Genetic association studies of complex traits: design and analysis issues
TL;DR: The different types of association studies are reviewed and issues that are important to consider are discussed when performing and interpreting association studies of complex genetic traits, which are all integral parts of a high-quality association study.

Inference of population structure using multilocus genotype data
TL;DR: Pritch et al. as discussed by the authors proposed a model-based clustering method for using multilocus genotype data to infer population structure and assign individuals to populations, which can be applied to most of the commonly used genetic markers, provided that they are not closely linked.

TL;DR: In this article, the authors used haplotype analysis of linkage disequilibrium to spotlight a small segment of 4p16.3 as the likely location of the defect, which is expanded and unstable on HD chromosomes.

TL;DR: The Huntington's disease mutation involves an unstable DNA segment, similar to those described in fragile X syndrome, spino-bulbar muscular atrophy, and myotonic dystrophy, acting in the context of a novel 4p16.3 gene to produce a dominant phenotype.
