AI Article Synopsis
- The chromosome 16p13.11 heterozygous deletion is linked to various neuropsychiatric disorders, but the effects of its duplication are less understood.
- Researchers analyzed 1645 pediatric patients with developmental disorders and found 4 deletions and 8 duplications in the 16p13.11 region, affecting about 0.73% of the patients.
- Common features among affected patients include intellectual disabilities, autism, seizures, and physical anomalies, indicating that duplications may also contribute to clinical issues.
Article Abstract
The chromosome 16p13.11 heterozygous deletion is associated with a diverse array of neuropsychiatric disorders including intellectual disabilities, autism, schizophrenia, epilepsy and attention-deficit hyperactivity disorder. However the clinical significance of its reciprocal duplication is not clearly defined yet. We evaluated 1645 consecutive pediatric patients with various developmental disorders by high-resolution microarray-based comparative genomic hybridization and identified four deletions and eight duplications within the 16p13.11 region, representing ∼0.73% (12/1645) of the patients analyzed. Recurrent clinical features in these patients include mental retardation/intellectual disability, autism, seizure, dysmorphic feature or multiple congenital anomalies. Our data expand the spectrum of the clinical findings in patients with these genomic abnormalities and provide further support for the pathogenic involvement of this duplication in patients who carry them.

While artificial light in urban environments was previously thought to override seasonality in humans, recent studies have challenged this assumption. We aimed to explore the relationship between seasonally varying environmental factors and changes in sleep architecture in patients with neuropsychiatric sleep disorders by comparing two consecutive years. In 770 patients, three-night polysomnography was performed at the Clinic for Sleep & Chronomedicine (St.

The neuronal ceroid lipofuscinoses (NCLs) are incurable pediatric neurodegenerative diseases characterized by accumulation of lysosomal material and dysregulation of autophagy. Given the promising results of treatment with trehalose, an autophagy inducer, in cell and animal models of NCL, we conducted an open-label, non-placebo-controlled, non-randomized 12-month prospective study in NCL patients receiving oral trehalose (4 g/day). All were treated with a commercially available formulation for 6 months, followed by a 6-month washout.

Importance: As an accessible part of the central nervous system, the retina provides a unique window to study pathophysiological mechanisms of brain disorders in humans. Imaging and electrophysiological studies have revealed retinal alterations across several neuropsychiatric and neurological disorders, but it remains largely unclear which specific cell types and biological mechanisms are involved.
Objective: To determine whether specific retinal cell types are affected by genomic risk for neuropsychiatric and neurological disorders and to explore the mechanisms through which genomic risk converges in these cell types.

Background: The tachykinin substance P (SP) facilitates learning and memory processes after its central administration. Activation of its different receptive sites, neurokinin-1 receptors (NK1Rs), as well as NK2Rs and NK3Rs was shown to influence learning and memory. The basal ganglia have been confirmed to play an important role in the control of memory processes and spatial learning mechanisms, and as part of the basal ganglia, the globus pallidus (GP) may also be involved in this regulation.
