Genetic aspects of lactase deficiency in indigenous populations of Siberia
The ability to metabolize lactose in adulthood is associated with the persistence of lactase enzyme activity. In European populations, lactase persistence is determined mainly by the presence of the rs4988235-T variant in the MCM6 gene, which increases ...

The biochemical and genetical analysis of lactase phlorizin hydrolase: with specific reference to the lactase persistence/ non-persistence polymorphism in man [PDF]
This thesis describes investigations on the biochemical and genetical properties of human intestinal lactase-phlorizin hydrolase which were designed to help in the understanding of the molecular basis of the lactase persistence / non-persistence ...
