Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...

Conduct disorder (CD) is a moderately heritable psychiatric disorder of childhood and adolescence characterized by aggression toward people and animals, destruction of property, deceitfulness or theft, and serious violation of rules. Genome-wide scans using linkage and association methods have identified a number of suggestive genomic regions that are pending replication. A small number of cand...

BACKGROUND/AIM Bipolar affective disorder is mental disorder with polygenic type of heredity. Heritability--relation between genetic and environmental variance is used to estimate the level of influence of genetic variance to phenotype variance. Study results show decreasing trend in the value of heritability of bipolar affective disorder, thus indicating that this disorder is a complex behavio...

EVALUATION OF THE PROTECTIVE ROLE HYDROALCOHOLIC EXTRACT GINGER AND N-ACETYLCYSTEINE ON GENETIC DISORDER CAUSED BY SODIUM AZIDE HUMAN BLOOD LYMPHOCYTES MICRONUCLEUS METHOD

Preimplantation genetic testing (PGT) involves analysis of biopsied cells as part of an assisted reproductive procedure. It is generally considered to be divided into 2 categories. Preimplantation genetic diagnosis (PGD) is used to detect a specific inherited disorder and aims to prevent the birth of affected children in couples at high risk of transmitting a disorder. Preimplantation genetic s...

Background Findings from family and twin studies suggest that genetic contributions to psychiatric disorders do not in all cases map to present diagnostic categories. We aimed to identify specifi c variants underlying genetic eff ects shared between the fi ve disorders in the Psychiatric Genomics Consortium: autism spectrum disorder, attention defi cit-hyperactivity disorder, bipolar disorder, ...

We aimed to identify specifi c variants underlying genetic eff ects shared between the fi ve disorders in the Psychiatric Genomics Consortium: autism spectrum disorder, attention defi cit-hyperactivity disorder, bipolar disorder, ...

BACKGROUND Subtle abnormalities in frontal white matter have been reported in bipolar disorder. AIMS To assess whether impaired integrity of white matter tracts is associated with bipolar disorder and genetic liability for the disorder. METHOD A total of 19 patients with psychotic bipolar I disorder from multiply affected families, 21 unaffected first-degree relatives and 18 comparison indi...
