De Novo 2.2 Mb 19q13.42–q13.43 Microdeletion Encompassing U2AF2: Support for a Haploinsufficiency Model

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...

Aicardi syndrome

CHRISMED Journal of Health and Research, 2018
Aicardi syndrome is a rare genetic disease characterized by a characteristic classical trio of neurological clinical abnormalities (spasms), agenesis of the corpus callosum, and ophthalmological abnormalities.

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.

Concordance of Prenatal Ultrasonography and Magnetic Resonance Imaging in the Classification of Corpus Callosum Dysplasia

Clinical and Experimental Obstetrics & Gynecology
Background: Prenatal ultrasound has always been difficult to classify fetal corpus callosum abnormalities. This paper aims to evaluate the added value of fetal magnetic resonance imaging (MRI) to ultrasound in detecting fetal corpus ...

Co‐Occurring Non‐Cardiac Congenital Anomalies Among Cases With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cases with congenital heart defects (CHD) often have other associated anomalies. The aim of this investigation was to assess the prevalence and the types of co‐occurring anomalies in CHD in a well‐defined population. The anomalies co‐occurring with CHD were ascertained in all live births, stillbirths and terminations of pregnancy for fetal ...

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Identification of major congenital malformations based on healthcare databases in France: A proof‐of‐concept study using the epi‐meres nationwide mother–child register

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Besides registries, healthcare databases can provide useful information for assessing the frequency of major congenital malformations (MCMs) and investigating their risk factors, particularly medication exposures. This study aimed to assess the validity of MCMs identification based on French national, comprehensive healthcare databases ...

Ketamine and Agenesis of the Corpus Callosum

Survey of Anesthesiology, 1979
Ketamine did not provide adequate anaesthesia for pneumoencephalography in a 10-week-old child with agenesis of the corpus collosum. Associated neurological defects are the most likely reason for this failure.

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

Agenesis of the corpus callosum associated with hereditary syndromes

Анналы клинической и экспериментальной неврологии, 2017
: Agenesis of the corpus callosum (ACC) is detected in patients with cerebral dysgenesis associated with various hereditary syndromes. It is conventionally subdivided into total (the absence of commissural fibers) and partial (agenesis of the rostral and
