This study shows geographic distribution of two lactase persistence variants in the African Sahel belt. We found that the variant –13910*T is situated west of Lake Chad and variant –13915*G east of there. Both are at the same time present only in the pastoralist and not farmer populations. Another important findings we made is that –13910*T lies on a more diversified haplotype among the Fulani than among the Tuareg. Interestingly, the age estimate for expansion of this variant among the Fulani corresponds with the first introduction of pastoralism to Africa. We therefore suggest that the origin of this variant could be in a region encompassing the Near East and northeastern Africa in a population ancestral to both first Saharan pastoralists and European farmers.
