Lactase Persistence in Central Asia: Phenotype, Genotype, and Evolution

Human Biology, 2011
The aim of the present study is to document the evolution of the lactase persistence trait in Central Asia, a geographical area that is thought to have been a region of long-term pastoralism. Several ethnic groups co-exist in this area: Indo-Iranian speakers who are traditionally agriculturist (Tajik) and Turkic speakers who used to be nomadic herders (

Hypolactasia and Lactase Persistence Historical Review and the Terminology

Scandinavian Journal of Gastroenterology, 1994
Lactase (more precisely lactase-phlorizin hydrolase) is located in the brush border of the small intestinal enterocytes and is responsible for the hydrolysis of dietary lactose. The earliest studies on lactase activity in mammals were published around the turn of the century.

Evolutionary genetics of lactase persistence in Italy.

2012
The enzyme that hydrolyzes lactose, the main carbohydrate in milk, is lactase-phlorizin hydrolase (LCT), which is encoded by the gene LCT located on chromosome 2. Normally, in all mammals, the ability to digest lactose rapidly declines after weaning, but in some human populations this ability persists in adulthood, a condition called lactase ...
