Glossary: Understanding STXBP1 and Related Terms
Find definitions and explanations for terms commonly used in STXBP1 research and our mission.
Munc-18
Definition: Munc-18 (short for mammalian uncoordinated-18) is a group of proteins that are very important for how nerve cells communicate with each other. These proteins help control the process of synaptic vesicle fusion, which is when tiny bubbles (vesicles) filled with chemicals (neurotransmitters) merge with the cell membrane to release…
STXBP1
Definition: STXBP1 disease, or STXBP1 encephalopathy, is a rare genetic neurological disorder caused by mutations in the STXBP1 gene. It leads to severe neurodevelopment issues, primarily affecting neurotransmitter release in the brain. Further information: Management and Treatment: Related Terms: FAQs: A genetic neurological disorder with severe developmental issues and seizures.…
Neurotransmitter
Definition: Neurotransmitters are chemical messengers used by the nervous system to transmit signals between neurons or from neurons to muscles. They facilitate communication across the synaptic cleft, where electrical signals are converted into chemical signals. Further information: Functions: Treatment: Related Terms: FAQs: Chemical messengers that transmit signals between neurons or…
Genome
Definition: A genome is the complete set of genetic information in an organism, consisting of nucleotide sequences of DNA (or RNA in some viruses). In humans, the genome includes 23 pairs of chromosomes located in the nucleus, containing all the information necessary for an individual to develop and function. Further…
Ataxia
Definition: Ataxia is a neurological condition characterised by a lack of muscle coordination and control, leading to clumsy or awkward movements. It can affect various body functions, including walking, balance, speech, and fine motor skills. Further information: Management and Treatment: Related Terms: FAQs: A neurological condition characterized by impaired muscle…
Intellectual Disability
Definition: Intellectual disability is a term used to describe a condition characterised by significant limitations in both intellectual functioning and adaptive behaviour. This means that individuals with intellectual disabilities may have challenges with learning, reasoning, problem-solving, and everyday skills necessary for independent living. Key Features: Causes: Intellectual disability can result…
Genetic Mutation
Definition: A genetic mutation is a permanent alteration in the DNA sequence of an organism’s genome. These changes can occur due to errors during DNA replication, exposure to environmental factors, or as a result of viral infections. Mutations can affect a single nucleotide or large segments of chromosomes. Types of…
Chromosome
Definition: A chromosome is a thread-like structure made of DNA and proteins that carries genetic information. Chromosomes are located in the nucleus of eukaryotic cells and play a crucial role in heredity, as they contain the instructions necessary for the growth, development, and functioning of an organism. Key Characteristics: Types…
Protein
Definition: Protein is a large, complex molecule made up of one or more long chains of amino acids. Proteins are essential for the structure, function, and regulation of the body’s tissues and organs. They perform a wide range of functions within organisms, including catalysing metabolic reactions, providing structural support, and…
Spasticity
Definition: Spasticity is a motor disorder characterized by a velocity-dependent increase in muscle tone or tonic stretch reflexes, resulting from upper motor neuron lesions. It presents as involuntary muscle overactivity, leading to stiffness and resistance to movement. Key Features: Management and Treatment: Medications: Therapies: Surgical Options: In severe cases, surgical…
