CHRNA4 (Cholinergic Receptor Nicotinic Alpha 4 Subunit) is a gene that encodes a subunit of the nicotinic acetylcholine receptor, which plays a key role in neurotransmission within the nervous system. This receptor is important for regulating neuronal excitability and synaptic communication. Mutations in CHRNA4 have been linked to certain types of epilepsy and other neurological disorders, underscoring its essential role in brain function.
