background: human leukocyte antigen-g (hla-g) is a non-classical class i molecule highly expressed by extravillous cytotrophoblast cells. due to a single base pair deletion, its function can be compensated by other isoforms. investigating the frequency of null allele in recurrent miscarriage (rm) subjects could be useful in understanding the relationship between frequency of this allele and rm ...

INFLUENCE OF A SEROTONIN TRANSPORTER PROMOTER POLYMORPHISM ON CORTICOLIMBIC ABNORMALITIES IN BIPOLAR DISORDER Maulik P. Shah, and Hilary P. Blumberg. Department of Psychiatry, Yale University School of Medicine, New Haven, CT. Bipolar disorder (BD) is associated with abnormalities of the subgenual anterior cingulate cortex (sgACC) and the amygdala, components of a corticolimbic neural system th...

Objective(s): Mutations in the UGT1A1 gene are responsible for hyperbilirubinemia syndromes including Crigler-Najjar type 1 and 2 and Gilbert syndrome. In view of the genetic heterogeneity and involvement of large numbers of the disease causing mutations, the application of polymorphic markers in the UGTA1 gene could be useful in molecular diagnosis of the disease. Materials and Methods: In the...

Individuals vary in their willingness to take financial risks. Here we show that variants of two genes that regulate dopamine and serotonin neurotransmission and have been previously linked to emotional behavior, anxiety and addiction (5-HTTLPR and DRD4) are significant determinants of risk taking in investment decisions. We find that the 5-HTTLPR s/s allele carriers take 28% less risk than tho...

The prevalence of a genetic polymorphism(s) at codon 268 in the cytochrome b gene, which is associated with failure of atovaquone-proguanil treatment, was analyzed in 227 Plasmodium falciparum parasites from western Kenya. The prevalence of the wild-type allele was 63%, and that of the Y268S (denoting a Y-to-S change at position 268) mutant allele was 2%. There were no pure Y268C or Y268N mutan...

BACKGROUND The short (s) allele of the serotonin transporter gene promoter (5-HTTLPR) may be associated with exposure to social adversities and the subsequent onset of depressive illness in adulthood. AIMS To test in adolescents at high risk for depression whether the short 's' allele is associated with levels of morning cortisol and the subsequent onset of a depressive episode. METHOD High...

BACKGROUND The glutathione thymidine repeats [(GT)n] of the heme oxygenase (HO)-1 gene promoter have been shown to be correlated with the incidence of coronary artery disease (CAD), patients with shorter repeats being less likely to have CAD. In this study, we investigated whether (GT)n repeats in the HO-1 promoter were related to a quantitative angiographic severity of CAD. METHODS The allel...

Objective(s): To investigate the association of single nucleotide polymorphisms (SNPs) in the peroxisome proliferator-activated receptors gamma (PPARG) with essential hypertension (EH) and additional role of gene– high-density lipoprotein cholesterol (HDL) interaction. Materials and Methods:A total of 1640 patients with EH (806 males, 834 females), with a mean age of 52.5±12.6 years, were selec...

Objective(s): Previous studies have reached different conclusions regarding an association between apolipoprotein E (APOE) polymorphisms and depression. This meta-analysis was designed to clarify these controversies. Materials and Methods: Literatures were identified reviewing the national and international databases. The eligible articles for meta-analysis were determined by quality assessment...
