  Genetic Association Database   (Site not responding. Last check: 2007-10-03)
The Genetic Association Database is an archive of human genetic association studies of complex diseases and disorders.
The goal of this database is to allow the user to rapidly identify medically relevant polymorphisms from the large volume of polymorphism and mutational data, in the context of standardized nomenclature.
The Genetic Association database is open to the public.

 American Genetic Association   (Site not responding. Last check: 2007-10-03)
On December 29-31, 1903, in St. Louis Missouri, a committee organized by the American Association of Agricultural Colleges and Experiment Stations held the first meeting to establish the constitution and by-laws of the new American Breeders Association.
It was in 1914 that the ABA became the American Genetic Association and implemented a business-model organization and strove for financial stability in order to minimize it's dependence on donations and the influence these donations might carry.
Today the American Genetic Association is publishing primary Genetics research in such fields as genomic diversity, comparative genetics, species conservation, polygenic and multi-factorial gene hunts, genetic epidemiology, bioinformatics, molecular evolution, plant and animal domestication, phylogenetics and phylogeography.

 ADHD Genetic Research -- Neurotransmitter.net
Association between ADHD and the 10-repeat allele of a 40-bp VNTR polymorphism that lies within the 3'-UTR of DAT1 was first reported in 1995, a finding that has been replicated in at least six independent samples from Caucasian populations.
Molecular genetic investigations of ADHD have found positive associations with the 480-bp allele of a VNTR situated in the 3' untranslated region of DAT1 and allele 7 of a VNTR in exon 3 of DRD4.
Associations of polymorphisms with ADHD and its subtypes were examined by: (i) comparing cases and controls; and (ii) using family-based association study in an extension of exact transmission-disequilibrium test (ETDT) and haplotype-based haplotype relative risk (HHRR).

 Genetic association studies/LD mapping
Association between phenotypes and marker loci is not only caused by marker loci being in LD with a disease locus but can also be due to population structure.
In general, LINKAGE is considered to be the association between alleles and disease WITHIN families, whilst genetic ASSOCIATION is thought of as the association between alleles and disease at the population level, ie beyond that which exists within families.
Testing/estimating phenotype-gene association using haplotypes is dealt with in estimation of haplotypes/testing and estimating phenotype-gene association.

 OJHAS: 2005-1-4; Menik HL et al. Genetic Association between Insulin Resistance and Total Cholesterol in Type 2 ...
We investigated the degree of genetic association between insulin resistance (IR) with type 2 diabetes mellitus (DM) and abnormalities in lipid metabolism in 42 patients.
We planned to identify the genetic association of IR with DM and the dyslipidemia because the data related to the prevalence and quantitative analysis of IR and prevalence of dyslipidemia among Sri Lankan diabetic population are not available.
Therefore, the association between elevated total cholesterol and IR could be due to the effects of IR on cholesterol metabolism or vice versa.

 [No title]
On the basis of observations of the deficits associated with sex chromosome aneuploidies there is a substantial case that the relevant gene is in the class that is present in homologous form on the X and Y chromosomes.
With genetically informative data, latent growth curve analyses permit one to investigate the extent to which variations in (1) the intercept, or mean level of drinking, and (2) the slope, representing change in the trait over time, are due to genetic and environmental influences.
Genetic and environmental sources of individual variation were assessed for masculine and feminine sex-typed behavior at 3 and again at 4 years of age as measured by parent reports on the Pre-school Activities Inventory (Golombok, S. & Rust, J.

association studies of 71 markers with obesity-related phenotypes.
In an association study confounded by population stratification, an association between marker and phenotype is observed (broken line).
However, the association is attributable to the unobserved admixture or subpopulations by which marker prevalence and phenotypic values vary together (solid lines).

 Genetic association studies in complex diseases   (Site not responding. Last check: 2007-10-03)
Genetic association studies are the most frequent type of study performed in the investigation of the genetic basis of complex cardiovascular conditions.
While relatively easy to perform, and having previously correctly identified genetic effects subsequently proven to be due to genetic linkage, interpretation of the results of these studies is not always straightforward.
Issues such as population stratification, data-driven subgroup analysis, possible absence of linkage disequilibrium between marker and disease locus, and testing of multiple hypotheses are discussed and the likely place for association studies in a strategy involving studies of a variety of designs geared to finding genetic determinants of disease susceptibility is addressed.
