Are There Genetic Factors in Suicide?

P30: Are There Anxious Genes?

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...

P-47: Are There any Predictive Factors for SuccessfulcessfulAnalysis of 339 Cycles

s:1454:"Background: Intracytoplasmic sperm injection(ICSI) outcome is tighly depending of male and female factors. The assessment of several clinical and laboratory parameters may predict results of ICSI. Materials and Methods: We restrospectively analysed patients who had ICSI for male or female factor infertility. The clinical and laboratory factors that influenced the fertilization, pregnanc...

Genetic risk factors and variation in European suicide rates.

Anxiety disorders and neuroticism: are there genetic factors specific to panic?

Data from 2,903 adult same-sex twin pairs were analysed to investigate whether the genetic determinants of symptoms of panic are different from those underlying the neuroticism personality trait. Our results suggest that much of the genetic variation influencing the physical symptoms associated with panic is of the nonadditive type, perhaps due to dominance or epistasis. In both sexes these non...

Commentary: why are there difficulties in controlling genetic variability?

More than 20 years ago, K. Gärtner published a paper in the journal Laboratory Animals. According to the author: ‘Reduction of genetic variability by using inbred strains and reduction of environmental variability by highly standardized husbandry in laboratory animals did not remarkably reduce the range of random variability in quantitative biological traits.’ As far as I can see, this statemen...
