Summary
Velocardiofacial syndrome, a 22q11.2 deletion disorder, impacts the central nervous system, causing psychiatric issues and cognitive impairments. Understanding gene roles in cognition requires considering genetic, developmental, and environmental factors.
Area of Science:
- Genetics
- Neuroscience
- Developmental Biology
Context:
- Chromosomal microdeletions, such as 22q11.2 deletion, are increasingly identified as causes of specific syndromes.
- Velocardiofacial syndrome (VCFS) results from a hemizygous deletion on chromosome 22q11.2, affecting approximately 40 genes.
- While VCFS causes systemic alterations, central nervous system effects are most significant, leading to a complex clinical presentation.
Purpose:
- To explore the molecular and clinical characterization of VCFS.
- To investigate the connection between the 22q11.2 deletion and cognitive and psychiatric manifestations.
- To understand the role of genes within the deleted region in human cognitive capacities.
Summary:
- The 22q11.2 deletion in VCFS leads to neurodevelopmental alterations, including psychiatric disorders, cognitive deficits, and language delay.
- Molecular characterization of deleted genes and the development of animal models have advanced the understanding of the VCFS phenotype.
- Gene effects on cognition are not direct but are modulated by molecular, ontogenetic, and environmental contexts.
Impact:
- Enhanced understanding of gene-environment interactions in cognitive development.
- Improved insights into the genetic basis of psychiatric disorders and cognitive impairments.
- Foundation for targeted research into VCFS and related neurodevelopmental conditions.

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

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...
01:25Introduction to Language of Pathophysiology l
Pathophysiology investigates how biological mechanisms—typically starting at the cellular level—disrupt normal bodily functions. It bridges anatomy and physiology to explain the progression of disease. With this foundation, it is important to understand the following key terms used to describe disease processes: Diagnosis:The process of identifying a disease using clinical evaluation, including signs (objective evidence like rashes), symptoms (subjective experiences like pain), laboratory test...
01:24Components of Language
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs. “eh”). Phonemes combine to...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
