Ethnic differences in CD1E, but not CD1A, gene polymorphisms between Sub-Saharan Africans, West Asians and Europeans.

The five closely linked CD1A-E genes encode the human CD1 family of proteins. Few studies of the allele frequencies of these genes in African populations have been published so far. This study aimed to genotype CD1A and CD1E variants and to compare their frequencies in Sub-Saharan Africans from Gabon and Ivory Coast, and Non-Africans from Syria and France.
