Twins in cardiovascular genetic research.
Twin studies have been largely responsible for showing the effects of genetic variance on a quantitative trait. The model is based on the fact that monozygotic twins share all genes in common, whereas dizygotic twins are related as siblings and share "on average" half their genes. Environmental confounders are minimized because twin children are usually exposed to similar environments. Blood pr...
متن کاملFrom twins to genetic polymorphisms: behavioral genetic research in Poland.
Behavioral genetic research has been conducted at the University of Warsaw for the past 20 years. The work done at the University focuses primarily on the origins of individual differences in temperament and other personality traits. In particular, research is directed toward the traits postulated in the Regulative Theory of Temperament. We also focused on the heritability of socio-political at...
متن کاملCardiovascular evaluation in thoracopagus twins.
Thoracopagus is the most common form of conjoined twins. Cardiovascular evaluation is necessary to establish the existence of 2 separate hearts before planning surgical separation of the twins. This is usually done by cardiac ultrasound, cardiac catheterization, documenting 2 separate pulse rates on physical examination, and the presence of 2 independent QRS complexes on simultaneously recorded...
متن کاملCongenital cardiovascular anomalies in twins.
G REAT advances have been made during the past 2 decades in methods of diagnosing congenital cardiovascular lesions, and in concepts and technics of their surgical correction. There has been almost no progress, however, in the prevention of such defects because of the paucity of knowledge about their causes. The anomalies in humans appear to be genetically determined in certain instances and to...
متن کاملDefining nicotine dependence for genetic research: evidence from Australian twins.
BACKGROUND Whether current criteria used to define nicotine dependence are informative for genetic research is an important empirical question. The authors used items of the DSM-IV and of the Heaviness of Smoking Index to characterize the nicotine dependence phenotype and to identify salient symptoms in a genetically informative community sample of Australian young adult female and male twins. ...
