Lactose digestion and the evolutionary genetics of lactase persistence.

Human genetics - 1 Jan 2009

Ingram Catherine J E, Mulcare Charlotte A, Itan Yuval, Thomas Mark G, Swallow Dallas M

Abstract excerpt

It has been known for some 40 years that lactase production persists into adult life in some people but not in others. However, the mechanism and evolutionary significance of this variation have proved more elusive, and continue to excite the interest of investigators from different disciplines. This genetically determined trait differs in frequency worldwide and is due to cis-acting polymorphism of regulation of...
