The Ig alpha is the major immunoglobulin class in body secretions. It may serve both to defend against local infection and to prevent access of foreign antigens to the general immunologic system. The Human alpha 1 and two allelic alpha 2 immunoglobulin heavy chain constant region genes contain three exons, each encoding a single constant region protein domain. Alignment of the alpha 1 and alpha 2 gene sequences reveals an unusual coupled deletion-duplication in the 5'- flanking region, which can be explained in terms of a slipped-strand mispairing model. Comparison of nucleotide sequences of the alpha 1 gene and two alleles of the alpha 2 gene indicates a localized transfer of genetic information from the 3' end of the alpha 1 gene to one of the alpha 2 alleles, probably by a gene conversion.
