Chromosomal localization of seven neuronal nicotinic acetylcholine receptor subunit genes in humans.
We have determined the chromosomal location of seven human neuronal nicotinic acetylcholine receptor subunit genes by genomic Southern analysis of hamster/human somatic cell hybrid DNAs. The beta 2 subunit gene was localized to human chromosome 1, the alpha 2 and beta 3 subunit genes were localized to human chromosome 8, the alpha 3, alpha 5, and beta 4 subunit genes were localized to human chromosome 15, and the alpha 4 subunit gene was localized to human chromosome 20. Mapping of the beta 2 subunit gene to chromosome 1 establishes a syntenic group with the amylase gene locus on human chromosome 1 and mouse chromosome 3, while mapping of the alpha 3 subunit gene to chromosome 15 confirms the existence of a syntenic group with the mannose phosphate isomerase gene locus on human chromosome 15 and mouse chromosome 9.
