The Phenotype/Genotype Correlation of Lactase Persistence among Omani Adults [PDF]

open access: yesOman Medical Journal, 2013
Objective: To examine the correlation of lactase persistence phenotype with genotype in Omani adults.Methods: Lactase persistence phenotype was tested by hydrogen breath test in 52 Omani Adults using the Micro H2 analyzer.

Ancient DNA analysis reveals high frequency of European lactase persistence allele (T-13910) in medieval central europe. [PDF]

open access: yesPLoS ONE, 2014
Ruminant milk and dairy products are important food resources in many European, African, and Middle Eastern societies. These regions are also associated with derived genetic variants for lactase persistence.

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.

Very low frequency of the lactase persistence allele LCT-13910T in the Armenian population

open access: yesAnnals of Human Biology, 2022
Primary lactose malabsorption is characterised by a down-regulation of lactase activity after weaning and inability to digest lactose in adulthood. It has been suggested that the historical introduction of dairying led to a positive selection for lactase

Human Genetics: Lactase Persistence in a Battlefield [PDF]

open access: yesCurrent Biology, 2020
Lactase persistence is a common genetic trait in Europeans and other pastoralists. New ancient DNA evidence from a Bronze Age battlefield indicates that selection for lactase persistence was strong and on-going in the last 3,000 years.

Comparative metabolomics in primates reveals the effects of diet and gene regulatory variation on metabolic divergence. [PDF]

open access: yes, 2014
Human diets differ from those of non-human primates. Among few obvious differences, humans consume more meat than most non-human primates and regularly cook their food.

Lactase persistence genotypes and malaria susceptibility in Fulani of Mali

open access: yesMalaria Journal, 2011
Background Fulani are a widely spread African ethnic group characterized by lower susceptibility to Plasmodium falciparum, clinical malaria morbidity and higher rate of lactase persistence compared to sympatric tribes.

Escape from epigenetic silencing of lactase expression is triggered by a single-nucleotide change [PDF]

open access: yes, 2016
The importance of subtle gene regulation and epigenetics in determining complex human traits is increasingly being recognized. However, bridging the gaps between environmental, epigenetic and genetic influences and unraveling causal relationships remain ...
