Summary
Children with PHACE syndrome often experience neurodevelopmental issues, including language and gross motor delays. Cerebral structural abnormalities are linked to poorer neurodevelopmental outcomes in these patients.
Area of Science:
- Pediatric Neurology
- Neurocutaneous Syndromes
- Developmental Pediatrics
Background:
- PHACE syndrome is a rare neurocutaneous disorder.
- Previous reports suggest neurodevelopmental abnormalities in affected children.
- Characterized in 1996, PHACE syndrome requires further investigation into its developmental impact.
Purpose of the Study:
- To investigate the prevalence and types of neurodevelopmental abnormalities in a cohort of children with PHACE syndrome.
- To identify potential associations between structural brain abnormalities and neurodevelopmental outcomes.
- To inform clinical practice and future research directions for PHACE syndrome.
Main Methods:
- Multicenter, retrospective study of 93 children diagnosed with PHACE syndrome (1999-2010).
- Detailed analysis of neurologic evaluations for 29 children aged ≥ 1 year (median age 4 years, 2 months).
- Correlation of neurodevelopmental outcomes with cerebral and posterior fossa structural abnormalities.
Main Results:
- 69% of evaluated children (20/29) exhibited neurodevelopmental abnormalities.
- Language delay (44%) and gross motor delay (36%) were most common; fine motor delay was less frequent (8%).
- Abnormal neurological exams were noted in 52%, with speech abnormalities being the most common finding. Cerebral structural abnormalities were significantly more frequent in children with abnormal neurodevelopmental outcomes (35% vs. 0%, P = .04).
Conclusions:
- Young children with PHACE syndrome referred for neurological evaluation frequently present with language and gross motor delays.
- Cerebral structural abnormalities may be associated with adverse neurodevelopmental outcomes in PHACE syndrome.
- Prospective studies are essential to elucidate the long-term neurodevelopmental trajectory in PHACE syndrome.

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
01:43Sex-linked Disorders
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
