GABRP
GABRB: A Key Player in Synaptic Signaling
Description
GABRB, also known as the GABA type B receptor, is a protein complex in the central nervous system that plays a crucial role in synaptic transmission. It belongs to the family of ligand-gated ion channels, which open in response to the binding of specific chemical messengers called neurotransmitters. In this case, the neurotransmitter is GABA (gamma-aminobutyric acid), an inhibitory neurotransmitter that reduces neuronal activity.
Associated Diseases
Mutations in the GABRB gene have been linked to a range of neurological disorders, including:
- Epilepsy: GABRB dysfunction can disrupt GABAergic signaling, leading to hyperexcitability in the brain and seizures.
- Intellectual disability: Mutations in GABRB have been associated with cognitive impairments and developmental delays.
- Autism spectrum disorder: Studies have suggested a possible link between GABRB variants and the development of autism.
- Multiple sclerosis: GABRB dysfunction may contribute to demyelination and neuronal damage in multiple sclerosis.
Did you Know ?
- Approximately 1 in 1,000 newborns have epilepsy related to GABRB mutations.
