Twin study of adolescent genetic susceptibility to mosquito bites using ordinal and comparative rating data.
Ordinal and comparative rating measures of mosquito attraction and mosquito bite frequency and symptoms were administered in a self-report questionnaire format to a sample of 197 monozygotic and 326 dizygotic Australian adolescent twin pairs at age 12 between 1992 and 1999, in order to investigate the environmental and possibly genetic determinants of variation between individuals. Repeat measu...
متن کاملGenetic epidemiology of epilepsy: a twin study.
The study explored the genetic susceptibility and prevalence of epilepsy in twins. The data on epilepsy were retrieved from the health records of 199 pairs of twins. Proband concordance rate in monozygotic (MZ) twins was four times more than that in dizygotic (DZ) twins (0.67 vs. 0.17). Three of 15 (20%) affected twin kinships had epileptic first-degree relatives. These findings indicated signi...
متن کاملTHE EFFECT OF GENETIC AL AND ENVIRONMENTAL FACTORS ON LIPIDS: A TWIN STUDY
To assess the relative contribution of genetic and environmental factors (particularly androgens) on circulating levels of lipid fractions, serum androgen and lipid fractions were measured in 34 pairs of female-female twins aged from 15- 45 years, some of whom were discordant for polycystic ovary syndrome (PCOS) diagnosed by ultrasound. Nineteen pairs were monozygotic twins (MZ) and 15 pai...
متن کاملGenetic Susceptibility to Acute Rheumatic Fever: A Systematic Review and Meta-Analysis of Twin Studies
BACKGROUND Acute rheumatic fever is considered to be a heritable condition, but the magnitude of the genetic effect is unknown. The objective of this study was to conduct a systematic review and meta-analysis of twin studies of concordance of acute rheumatic fever in order to derive quantitative estimates of the size of the genetic effect. METHODS We searched PubMed/MEDLINE, ISI Web of Scienc...
متن کاملGenetic Susceptibility to Transient and Permanent Neonatal Diabetes Mellitus
Neonatal diabetes mellitus (NDM) is a rare kind of diabetes characterized by hyperglycemia and low levels of insulin. Clinically, it is categorized into two main types: transient NDM (TNDM) and permanent NDM (PNDM). These types are diagnosed based on duration of insulin dependence early in the disease. In TNDM, diabetes begins in the first few weeks of life with remission in a few months. Howev...
