Four common alleles HS1,2\u2010A*1, *2, *3, *4 are directly implicated with the transcription level and at least one of them, HS1, 2\u2010A*2, seems to be related to immune disorders, such as coeliac disease, herpetiform dermatitis and Berger syndrome. Given their clinical significance it is of interest to know the distribution of HS1,2\u2010A variants in populations from different continents, as well as to determine whether the polymorphism is associated to specific evolutionary factors. In this paper we report the distribution of the HS1,2\u2010A polymorphism in 1098 individuals from various African, Asian and European populations. HS1,2\u2010A*3 and HS1,2\u2010A*4 alleles are at their highest frequencies among Africans, and HS1,2\u2010A*2 is significantly lower in Africans in comparison with both Europeans and, to a lesser extent, Asians. Analysis of molecular variance of the allele frequencies indicates that the HS1,2\u2010A polymorphism can be considered as a reliable anthropogenetic marker.<\/jats:p>","DOI":"10.1111\/j.1469-1809.2006.00273.x","type":"journal-article","created":{"date-parts":[[2006,10,11]],"date-time":"2006-10-11T03:28:13Z","timestamp":1160537293000},"page":"946-950","source":"Crossref","is-referenced-by-count":20,"title":["Immunoglobulin Enhancer HS1,2 polymorphism: a new powerful anthropogenetic marker"],"prefix":"10.1111","volume":"70","author":[{"given":"V.","family":"Giambra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Mart\u00ednez\u2010Labarga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Giufre'","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Modiano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Simpore'","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.
