The first "classical" twin study? Analysis of refractive error using monozygotic and dizygotic twins published in 1922.
The first classical twin studies, recognizing the potential of comparing findings in identical twins, have previously been reported to be those by Siemens and by Merriman, both published in 1924. However, we would like to bring to attention a study performed by Walter Jablonski, 2 years earlier (1922), investigating the contribution of heredity to refraction in human eyes. Jablonski examined th...
متن کاملFetal fraction estimate in twin pregnancies using directed cell-free DNA analysis.
OBJECTIVE To estimate fetal fraction (FF) in monozygotic and dizygotic twin pregnancies. METHODS Maternal plasma samples were obtained from 35 monochorionic twin pregnancies with male fetuses (monozygotic) and 35 dichorionic pregnancies discordant for fetal sex (dizygotic) at 11-13 weeks' gestation. Cell-free DNA was extracted and chromosome-selective sequencing with digital analysis of selec...
متن کاملDo we need more twin studies? The Healthy Twin Study, Korea.
The success of the Human Genome Project and recent technological progress have made the analysis of individual genetic variation much more feasible. However, genetic variations responsible for common complex human diseases and traits are largely unknown, with a few exceptions of specific subtype of common diseases (e.g. early onset type diabetes or Alzheimer disease). 1 Twin study has evolved f...
متن کاملGenetic Analysis of Blood Pressure and Anthropometric Measures Among North Indian Twins
Twin investigation has played a major role in the history of human genetics. The present cross-sectional study was undertaken on 50 pairs of monozygotic and dizygotic (8 monozygotic and 42 dizygotic) aged 7-67 years in Amritsar district in Punjab. Results from twin studies indicate that all the means of height, weight, systolic blood pressure, diastolic blood pressure, waist circumference, hip ...
متن کاملZygosity Misclassification of Recent Young Twins by Maternal Reports in Japan
The problem of zygosity misclassification of twins has been paid little attention in Japan. By analyzing maternal reports collected using an internet questionnaire, the author found that around 30% of monozygotic twins were misclassified as dizygotic twins, mainly by obstetricians. On the other hand, the percentage of dizygotic twin pairs misclassified as monozygotic twins was lower. Misclassif...
