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 ...

A Population‐Based Study of Limb Body Wall Complex With Proposed Features for Prenatal Diagnosis

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Limb body wall complex (LBWC) is a lethal condition comprising major congenital anomalies. Although currently diagnosed in the early prenatal period, historical diagnostic criteria are based on detailed pathological assessments. Prenatal and postnatal findings of LBWC and their phenotypic overlap with body stalk anomaly (BSA) and recurrent ...

Maternal Sirolimus Treatment Reverses Cardiac Rhabdomyoma‐Induced Hydrops Fetalis in a Twin Gestation With Tuberous Sclerosis Complex

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cardiac rhabdomyomas are often the presenting sign of tuberous sclerosis complex (TSC). Prior reports have shown that maternal sirolimus treatment can reduce rhabdomyomas. We used maternal sirolimus to reverse hydrops fetalis due to a massive cardiac rhabdomyoma in a twin gestation.

The Multifaceted Etiology of Mental Disorders With a Focus on Trace Elements, a Review of Recent Literature

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Mental disorders are a significant global public health concern, affecting nearly one in eight individuals worldwide. This review investigates the multifaceted etiology of mental disorders—specifically major depressive disorder (MDD), schizophrenia (SCZ), and bipolar disorder (BD)—through genetic, neurobiological, and environmental ...

The origin of monozygotic twinning

Reproductive BioMedicine Online, 2002
The incidence of monozygotic twinning appears to be increasing within the field of assisted human reproduction. Many theories have been put forward as to how and when this occurs. Whatever the cause, the normal events of embryo development, which necessarily involve axis formation, patterning and polarization, need to be adhered to in order to obtain a
