NEUROD2-related disorder with neonatal onset: case report and review of the literature [PDF]

Exploration of Neuroprotective Therapy
The NEUROD2 gene encodes a transcription factor essential for neuronal differentiation and cortical development. Pathogenic variants cause a rare autosomal dominant neurodevelopmental disorder with variable expressivity, typically presenting in early ...

TTC21B: From Modifier to Causative Gene in Joubert Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic pathogenic variants in TTC21B, encoding the retrograde intraflagellar transport protein IFT139, are a known cause of renal and skeletal ciliopathies. Single heterozygous variants in this gene were found to be enriched in a cohort of patients with various ciliopathy phenotypes, including three individuals with Joubert syndrome (JS), a

NEONATAL HYPOTONIA CAN BE A SODIUM CHANNELOPATHY: RECOGNITION OF A NEW PHENOTYPE [PDF]

Neurology, 2008
A 23-year-old French woman had an uncomplicated labor producing a male infant by vaginal delivery (case 4-2 in the table). The initial Apgar score was 10 but very rapidly he developed generalized hypotonia with impaired suckling. Respiration was initially uncompromised.

A Novel Homozygous Nonsense Variant in DCHS1 in a Brazilian Patient With Van Maldergem Syndrome Type 1: Clinical Report and Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Van Maldergem syndrome (VMLDS) is an ultra‐rare autosomal recessive disorder characterized by craniofacial dysmorphism, intellectual disability, hypotonia, skeletal anomalies, and feeding difficulties. It is caused by biallelic variants in DCHS1 or FAT4 genes.

Influence of Molecular Genetic Classes on Behavior in Prader‐Willi Syndrome

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT A wide range of behavioral phenotypes has been described in PWS patients including autism spectrum disorder (ASD). The prevalence of behavioral disorders was studied in 292 participants over 3 years with genetically confirmed PWS (N = 164 females and N = 128 males) with deletion (N = 182) and mUPD (maternal uniparental disomy) (N = 99).

Neonatal muscular manifestations in mitochondrial disorders

, 2011
During the last decade rapid development has occurred in defining nuclear gene mutations causing mitochondrial disease. Some of these newly defined gene mutations cause neonatal or early infantile onset of disease, often associated with severe ...

Extending the ATP9A‐Related Phenotypic Spectrum: Indication of Schizophrenia Susceptibility

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT ATP9A, which belongs to the P4‐ATPase family of proteins, is involved in the efficient transport of vesicles from the Golgi apparatus to the plasma membrane, as well as the release of extracellular vesicles from human cells. In 2021, a loss‐of‐function variant of this gene was identified as being associated with a recessive neurodevelopmental ...

Biallelic PIGB Variants Cause Motor Neuropathy with Conduction Blocks and Peripheral Nerve Hyperexcitability

Annals of Neurology, EarlyView.
Objective Glycosylphosphatidylinositol (GPI)‐anchored proteins play critical roles in nervous system function. Pathogenic variants in genes involved in GPI‐anchor biosynthesis cause early‐onset multisystem disorders known as inherited GPI deficiencies. We describe a novel neuromuscular phenotype associated with PIGB deficiency.
