Apert's syndrome with central nervous system anomalies
Acta Neuropathologica
|October 1, 1979
Summary
Apert syndrome involves brain developmental anomalies, particularly in the rhinencephalon (olfactory bulb and tract). These central nervous system malformations correlate with facial and cranial vault abnormalities.
Area of Science:
- Neuroscience
- Developmental Biology
- Medical Genetics
Background:
- Apert syndrome is a genetic disorder characterized by premature fusion of skull bones (craniosynostosis) and distinctive facial features.
- Understanding the central nervous system (CNS) anomalies associated with Apert syndrome is crucial for comprehensive patient care.
Observation:
- This study details the pathologic anatomy of the CNS in a patient diagnosed with Apert syndrome.
- Specific attention was given to malformations within the rhinencephalon, including organizational disturbances.
Findings:
- Multiple developmental anomalies of the brain were identified in the Apert syndrome patient.
- The findings highlight disturbances in rhinencephalic organization, linking CNS maldevelopment to craniofacial structures.
Implications:
- The observed rhinencephalic maldevelopment reinforces known associations between the olfactory system and facial/cranial vault development.
- Further research into CNS-involvement in Apert syndrome can improve diagnostic and therapeutic strategies.

Pleiotropy
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,...
Neurulation
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...
Prosopagnosia
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...
Autism 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.

Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
