NSD2 Coordinates the Neurogenic‐to‐Gliogenic Transition via H3K36me2‐Dependent Activation of the EGFR‐ERK Pathway

Advanced Science, EarlyView.
NSD2 coordinates the neurogenic‐to‐gliogenic transition in the developing neocortex through H3K36me2‐dependent activation of EGFR–ERK signaling. Loss of NSD2 disrupts astroglial and oligodendroglial development, whereas ERK activation rescues gliogenic defects in vitro and in vivo.

Gestational Hypoxia Disrupts Medial Ganglionic Eminence Progenitor Dynamics and Interneuron Development in Schizophrenia

Advanced Science, EarlyView.
FES‐derived MGE spheroids exhibit progenitor‐stage alterations in developmental trajectory and hypoxia‐responsive transcriptional programs, followed by functional disruption. Gestational hypoxia recapitulates impaired progenitor proliferation, shortened cell‐cycle progression, interneuron developmental abnormalities, and schizophrenia‐like behaviors in

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.

A Novel Splice Variant in ERGIC1 Causes Arthrogryposis Multiplex Congenita—Characterization Using Urine‐Derived Cells

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis multiplex congenita (AMC) is defined as the presence of joint contractures affecting at least two body regions at birth. Three different ERGIC1 variants have been reported in individuals with AMC. Here, we report on a 16‐year‐old male with a homozygous ERGIC1 c.250+1G>A variant that was classified as a variant of uncertain ...

Maternal‐Fetal Administration of Risdiplam Partially Rescues the SMNΔ7 Mouse Model of Spinal Muscular Atrophy

Annals of Neurology, EarlyView.
Objective Spinal muscular atrophy (SMA) is caused by deletions or mutations in the survival motor neuron 1 (SMN1) gene and subsequent reduction in the expression of survival motor neuron (SMN) protein. The disease is characterized by degeneration of α motor neurons and subsequent muscle atrophy.

Ontogeny of murine bony semicircular canal form

The Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...
