The Origins of Lactase Persistence in Europe

open access: goldPLoS Computational Biology, 2009
Lactase persistence (LP) is common among people of European ancestry, but with the exception of some African, Middle Eastern and southern Asian groups, is rare or absent elsewhere in the world.

Dairying, diseases and the evolution of lactase persistence in Europe [PDF]

open access: yesNature, 2022
In European and many African, Middle Eastern and southern Asian populations, lactase persistence (LP) is the most strongly selected monogenic trait to have evolved over the past 10,000 years1. Although the selection of LP and the consumption of prehistoric milk must be linked, considerable uncertainty remains concerning their spatiotemporal ...

A worldwide correlation of lactase persistence phenotype and genotypes [PDF]

open access: yesBMC Evolutionary Biology, 2010
Background The ability of adult humans to digest the milk sugar lactose - lactase persistence - is a dominant Mendelian trait that has been a subject of extensive genetic, medical and evolutionary research.

Ileal Lactase Expression Associates with Lactase Persistence Genotypes. [PDF]

open access: yesNutrients, 2021
(1) Background: Lactose digestion depends on persistence genotypes (including rs4988235), the frequency of which exhibits broad geographical variability.

The evolution of lactase persistence [PDF]

open access: yesAntropologia Portuguesa, 2012
Lactase persistence has long been recognized as a striking example of human dietary adaptation to changes in food production habits. The observation that the prevalence of lactase persistence is positively correlated with the cultural history of dairying

Impact of selection and demography on the diffusion of lactase persistence. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:The lactase enzyme allows lactose digestion in fresh milk. Its activity strongly decreases after the weaning phase in most humans, but persists at a high frequency in Europe and some nomadic populations.

The Genetic Variation of Lactase Persistence Alleles in Sudan and South Sudan. [PDF]

open access: yesGenome Biol Evol, 2021
Lactase persistence (LP) is a well-studied example of a Mendelian trait under selection in some human groups due to gene-culture coevolution. We investigated the frequencies of genetic variants linked to LP in Sudanese and South Sudanese populations ...

World-wide distributions of lactase persistence alleles and the complex effects of recombination and selection [PDF]

open access: yesHuman Genetics, 2017
The genetic trait of lactase persistence (LP) is associated with at least five independent functional single nucleotide variants in a regulatory region about 14 kb upstream of the lactase gene [-13910*T (rs4988235), -13907*G (rs41525747), -13915*G ...

Strain-Level Analysis of Bifidobacterium spp. from Gut Microbiomes of Adults with Differing Lactase Persistence Genotypes [PDF]

open access: yesmSystems, 2020
One of the strongest associations between human genetics and the gut microbiome is a greater relative abundance of Bifidobacterium in adults with lactase gene (LCT) single nucleotide polymorphisms (SNPs) associated with lactase nonpersistence (GG ...
