TLDR
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

TL;DR: The results suggest that the polymorphisms rs3746544 and rs1051312 may increase the odds of developing ADHD.

Immunogenetic surveillance of HIV/AIDS.
TL;DR: It is likely that rapid co-evolution of HIV-1 immune escape variants together with an adjustment of human immune response gene profiles has occurred in some exposed populations and could provide a rational platform for the design of future vaccines aimed at controlling the current AIDS pandemic.

Interpretation of simultaneous linkage and family-based association tests in genome screens.
TL;DR: It is concluded that when linkage and association tests are applied in the same data, the type I error rate of neither test will be affected and that power can be increased by applying tests conditionally.
Journal ArticleDOI
Population-based gene discovery in the post-genomic era.
TL;DR: The impact on LD and GRR of studying an isolated (also termed 'founder' or 'homogeneous') population, such as Ashkenazi Jews, as compared to an outbred Population of Caucasians is described.

Candidate gene approach in association studies : would the factor V Leiden mutation have been found by this approach?

TL;DR: One haplotype was clearly more frequent in patients than controls (GAAT; 20 versus 9%), suggesting that a polymorphism in or near the F5 gene in this haplotype is associated with an increased thrombotic risk.

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.
