Velo-Cardio-Facial Syndrome

Area of Science:

• Genetics
• Neuroscience
• Medical Genetics

Background:

• Velocardiofacial syndrome (VCFS), also known as DiGeorge syndrome, results from a 22q11.2 microdeletion.
• It encompasses over 200 physical anomalies, including cardiac and palate issues.
• Neuropsychiatric disorders and learning disabilities are significant challenges in VCFS patients.

Purpose of the Study:

• To review the historical context and current molecular findings of Velocardiofacial syndrome.
• To explore the association between the 22q11.2 microdeletion and the syndrome's physical and neuropsychiatric phenotypes.
• To highlight VCFS as a key genetic risk factor for schizophrenia.

Main Methods:

• Literature review of historical clinical reports.
• Analysis of molecular findings related to genes in the 22q11.2 deletion region.
• Examination of the physical and neuropsychiatric manifestations in VCFS.

Main Results:

• VCFS is linked to a microdeletion on chromosome 22 long arm.
• The syndrome presents a broad spectrum of over 200 physical anomalies.
• Learning disabilities and neuropsychiatric disorders, including schizophrenia-like psychosis, are prominent VCFS features.

Conclusions:

• VCFS is a common genetic disorder with significant physical and neuropsychiatric impact.
• Up to one-third of individuals with VCFS develop schizophrenia-related psychotic disorders.
• Identifying genetic, cognitive, and psychiatric risk factors for VCFS-associated schizophrenia is a critical research area.
