Other Information

**Key characteristics:** * The CHRNA2 gene is located on chromosome 15q21.1. * It is a large gene, encoding a protein of 1,331 amino acids. * The protein is a transmembrane protein that is expressed in a variety of cell types. * It is a ligand-gated channel, which means that it opens when a specific ligand binds to it. **Pathways and functions:** * The CHRNA2 gene is expressed in neurons throughout the body, including the central nervous system, the peripheral nervous system, and the autonomic nervous system. * In the central nervous system, the CHRNA2 gene is expressed in neurons of the brain and spinal cord. * In the peripheral nervous system, the CHRNA2 gene is expressed in neurons of the eyes, ears, nose, mouth, and throat. * In the autonomic nervous system, the CHRNA2 gene is expressed in neurons of the sympathetic and parasympathetic nervous systems. **Clinical significance:** * Mutations in the CHRNA2 gene have been linked to a number of neurological and psychiatric disorders, including schizophrenia, autism, and epilepsy. * These mutations can lead to the expression of a truncated protein that is unable to function properly. * This can result in abnormal neural function, which can lead to a variety of symptoms, including muscle weakness, difficulty speaking, and seizures. **Additional information:** * The CHRNA2 gene is a member of the nicotinic acetylcholine receptor family. * Nicotinic acetylcholine is a neurotransmitter that is involved in a variety of cellular processes, including muscle contraction, neurotransmission, and sensory perception. * The CHRNA2 gene is a highly calcium-sensitive channel. * Mutations in the CHRNA2 gene have been linked to a number of neurological and psychiatric disorders.
