title: New allele variants of the immunoglobulin switch (Salpha) regions.
abstract: In this report we define ten Salpha1 IGHA1 (*S5-*S14) and nine Salpha2 IGHA2 (*S10-*S18) newly found alleles of the human immunoglobulin switch alpha 1 and switch alpha 2 regions, respectively, in Colombian Indian, Black and Mestizo populations, and a complete list of the SacI and PvuII alleles so far identified as given.
