The T/G−13915 variant upstream of the lactase gene ( <i>LCT</i> ) is the founder allele of lactase persistence in an urban Saudi population

Abstract

The T/G-13915 variant is the founder mutation of lactase persistence in an urban Saudi population. The results obtained here have implications for genetic testing of adult-type hypolactasia and to analysis of human evolution, the origin of cattle domestication and migrations of the populations in the Arabian peninsula.
