Gene: CHRNA3

Alternate names for this Gene: BAIPRCK|LNCR2|NACHRA3|PAOD2

Gene Summary: This locus encodes a member of the nicotinic acetylcholine receptor family of proteins. Members of this family of proteins form pentameric complexes comprised of both alpha and beta subunits. This locus encodes an alpha-type subunit, as it contains characteristic adjacent cysteine residues. The encoded protein is a ligand-gated ion channel that likely plays a role in neurotransmission. Polymorphisms in this gene have been associated with an increased risk of smoking initiation and an increased susceptibility to lung cancer. Alternatively spliced transcript variants have been described.

Gene is located in Chromosome: 15

Location in Chromosome : 15q25.1

Description of this Gene: cholinergic receptor nicotinic alpha 3 subunit

Type of Gene: protein-coding

Gene: CHRNA5

Alternate names for this Gene: LNCR2

Gene Summary: The protein encoded by this gene is a nicotinic acetylcholine receptor subunit and a member of a superfamily of ligand-gated ion channels that mediate fast signal transmission at synapses. These receptors are thought to be heteropentamers composed of separate but similar subunits. Defects in this gene have been linked to susceptibility to lung cancer type 2 (LNCR2).
