Variations in genome-wide gene expression in identical twins – a study of primary osteoblast-like culture from female twins discordant for osteoporosis

BMC Genetics, 2004
Background Monozygotic twin pairs who are genetically identical would be potentially useful in gene expression study for specific traits as cases and controls, because there would be much less gene expression variation within pairs compared to two ...

Handedness in twins: meta-analyses

BMC Psychology, 2022
Background In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii)

Genetic and environmental influences on sleep quality, ability to settle, and crying duration in 2‐ and 5‐month‐old infants: A longitudinal twin study

JCPP Advances, EarlyView.
This study found that genetic factors largely influence crying duration and settle ability in infancy, while shared environmental factors primarily affect the number of night wakeups. Etiological influences tended to change from 2 to 5 months, reflecting a highly plastic period in infant brain development and in child‐environment interactions. Abstract

Chromosome 22q11.2 microdeletion in monozygotic twins with discordant phenotype and deletion size

Molecular Cytogenetics, 2012
We report on a pair of male monozygotic twins with 22q11.2 microdeletion, discordant phenotype and discordant deletion size. The second twin had findings suggestive of DiGeorge syndrome, while the first twin had milder anomalies without any cardiac ...
