Examining the association between cognitive ability and emotional problems across childhood using a genetically informative design: could there be a causal relationship?

Journal of Child Psychology and Psychiatry, EarlyView.
Background Emotional problems co‐occur with difficulties in verbal and nonverbal cognitive ability, yet the pathways underlying their association remain poorly understood: It is unclear whether effects may be causal, and to what extent they may run from cognition to emotion, or vice versa.

Predicting adolescent disordered eating and behaviours: exploring environmental moderators of polygenic risk

Journal of Child Psychology and Psychiatry, EarlyView.
Background Both genetic and environmental factors contribute to the risk of developing disordered eating, with twin studies demonstrating environmental factors moderate genetic susceptibility. To date, gene–environment interactions leveraging polygenic risk scores (PRS) have not been studied in disordered eating phenotypes beyond anorexia nervosa (AN).

Disease-associated epigenetic changes in monozygotic twins discordant for schizophrenia and bipolar disorder

Human Molecular Genetics, 2011
Studies of the major psychoses, schizophrenia (SZ) and bipolar disorder (BD), have traditionally focused on genetic and environmental risk factors, although more recent work has highlighted an additional role for epigenetic processes in mediating ...

Maternal expressions of warmth and negativity and adolescent mental health: using longitudinal monozygotic twin‐difference analyses to approach causal inference

Journal of Child Psychology and Psychiatry, EarlyView.
Background Emotions that mothers express about their offspring are associated with offspring mental health during childhood, but little research has explored whether this extends into adolescence. We investigated associations between maternal warmth and negativity towards twin offspring at age 10, and subsequent mental health outcomes in early and late

Viruses in the fecal microbiota of monozygotic twins and their mothers

Nature, 2010
Viral diversity and life cycles are poorly understood in the human gut and other body habitats. Phages and their encoded functions may provide informative signatures of a human microbiota and of microbial community responses to various disturbances, and ...

Two's company: Monozygotic twinning in the small‐spotted catshark (Scyliorhinus canicula)

Journal of Fish Biology, EarlyView.
Abstract Developmental abnormalities in elasmobranchs (sharks and rays) are rarely documented, with reported cases primarily involving fin or cranial deformities. Monozygotic twinning, the formation of identical twins from a single zygote, is particularly rare in these species and has been observed overwhelmingly in viviparous elasmobranchs.

Geographic Tongue in Monozygotic Twins

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2014
This article discusses a case of 5-year-old girl monozygotic twins who were suffering from geographic tongue (GT), a benign inflammatory disorder of the tongue which is characterized by circinate, irregular erythematous lesions on the dorsum and lateral borders of the tongue caused by loss of filiform papillae of the tongue epithelium.

Monozygotic twins discordant for low-level mosaic trisomy 17 at amniocentesis in a pregnancy with a favorable outcome and a literature review of heterokaryotypic monozygotic twins at amniocentesis

Taiwanese Journal of Obstetrics & Gynecology, 2020
Objective: We present a set of twins discordant for low-level mosaic trisomy 17 at amniocentesis, and we review the literature of heterokaryotypic monozygotic twins at amniocentesis.
