Identical twins carry a persistent epigenetic signature of early genome programming

Nature Communications, 2021
Monozygotic (MZ) twins and higher-order multiples arise when a zygote splits during pre-implantation stages of development. The mechanisms underpinning this event have remained a mystery.

Association of cumulative early medical events and neurodevelopmental conditions through a common latent factor—A population‐based twin study

JCPP Advances, EarlyView.
Abstract Background The cumulative effect of early medical events has been shown to be associated with autism. It is unclear whether this effect is specific to autism or if it is associated to other neurodevelopmental conditions (NDCs) as well. Methods We established a registry‐linked population‐based twin cohort of 10,254 pairs within the child and ...

Monozygotic Heterocaryotic Twinning [PDF]

Acta geneticae medicae et gemellologiae, 1974
Since the first publication in 1961, cases of monozygotic heterocaryotic twinning have been repeatedly found and a total of 14 observations can now be analysed. The mechanism involved in this type of twinning is yet uncertain and eventually is not identical in each case, the main uncertainty being to decide whether the chromosomal error affecting one ...

Methylomic analysis of monozygotic twins discordant for autism spectrum disorder and related behavioural traits

Molecular Psychiatry, 2013
Autism spectrum disorder (ASD) defines a group of common, complex neurodevelopmental disorders. Although the aetiology of ASD has a strong genetic component, there is considerable monozygotic (MZ) twin discordance indicating a role for non-genetic ...

Pathogenesis of Vitiligo: Integrating Immune and Non‐Immune Cell Crosstalk

The Journal of Dermatology, EarlyView.
ABSTRACT Vitiligo is an acquired autoimmune disease characterized by depigmented macules resulting from melanocyte loss. It is a complex multifactorial disorder in which genetic predisposition is combined with environmental factors; however, its detailed etiology remains unclear.

Differentiation between palatal rugae patterns of twins by means of the Briñón method and an improved technique

Brazilian Oral Research, 2017
Palatal rugae patterns are anatomic structures considered unique to each person. Monozygotic twins present similarities, however, Rugoscopy in particular, may contribute to their individualization for forensic purposes.

Associations Between Cognitive Functions and Subsequent Mood Disorder Prognosis in Low‐Risk, High‐Risk and Affected Monozygotic Twins: A Seven‐Year Follow‐Up Study

Acta Psychiatrica Scandinavica, EarlyView.
ABSTRACT Introduction Aberrant cognition is common among individuals at familial risk for mood disorders (MD) and those already affected. However, long‐term prospective studies are needed to determine whether specific cognitive features predict illness onset and relapse; and whether cognitive impairments reflect neurodevelopmental traits or ...

Prenatal growth markers in schizophrenia: a monozygotic co-twin control study. [PDF]

, 1996
OBJECTIVE: This co-twin study investigated monozygotic twins who were discordant for schizophrenia for evidence of prenatal growth differences between the affected and well co-twins. METHOD: Four dermatoglyphic markers of prenatal growth were obtained by

Research with twins: The concept of emergenesis. [PDF]

, 1982
Preliminaty findings from an on-going study of monozygotic twins reared apart (MZA) and data from a larger sample of twins reared together (MZT and DZT), indicate a surprisingly strong influence of genetic variation on aptitudes, psychophysiological ...
