intercellular adhesion molecule-1 (icam-1) lys469glu (k469e) polymorphism and gly 241arg (g241r) polymorphism might play important roles in cancer development and progression. however, the results of previous studies are inconsistent. the aim of this study was to evaluate the association between icam-1 k469e and g241r polymorphisms and the risk of cancer by meta-analysis.a comprehensive literat...

Association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. This study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. This investigation was performed using 77 barley genotypes and AFLP markers. In phenotypic evaluation, reaction of seedlings to powdery mild...

the molecular mechanisms of the fact that more than 50% of the individuals with the same genetic make up (e.g. identical twins in schizophrenia) do not show the same psychiatric phenotype remained undefined in psychiatry. this along with the failure to find responsible genes with major effects in psychiatric disorders and lack of consistency of genetic association studies led to the current una...

Background: Several studies investigated the association of ACE I/D polymorphism with the risk and severity of COVID-19 infection.  However, the information in each of the published studies is limited, and the results were inconsistent or even contradictory. Accordingly, this meta-analysis evaluated the association between the ACE I/D polymorphism and COVID-19 susceptibility and severity. Metho...

introduction: domestic animals are invaluable resources to study the molecular architecture of complex traits. although the mapping of quantitative trait loci (qtl) underlying economically important traits in domestic animals has achieved remarkable results in recent decades, not all of the genetic variation in the complex traits has been captured due to the low density of markers used in qtl m...

genetic epidemiological studies strongly suggest that additive and interactive genes, each with small effects, mediate the genetic vulnerability for schizophrenia. with the human genome working draft at hand, candidate gene (and ultimately large-scale genome-wide) association studies are gaining renewed interest in the effort to unravel the complex genetics of schizophrenia. linkage and fine ma...

Background: Vitiligo is an acquired, idiopathic, and common depigmentation disorder of the skin that affects people of all ages and both sexes equally in the worldwide. Although etiology of the disease is unknown, there are theories such as environment and genetic factors. Methods: In this article, we collected and summarized the appropriate manuscripts regarding the epidemiology and gene...

helicobacter pylori (h. pylori) plays an important role in the development of peptic and duodenal ulcerations as well as gastric cancer. several studies have shown a strong association between specific genotypes of h. pylori and gastrointestinal tract diseases. the vaca and caga genes, which are the putative virulence factors of the bacterium, are important determinants of h. pylori-related dis...

background: indigenous chickens could serve as precious genetic resources that should be considered in conservation and breeding programs. the major histocompatibility complex (mhc) has a strong association to disease resistance/susceptibility, production and reproduction traits in chicken. therefore, identifying its polymorphism in populations under selective breeding could be used for selecti...
