Top best answers to the question «Ethiopians dna high altitude»

  • One factor that may enable Ethiopians to tolerate high altitudes and hypoxia is the endothelin receptor type B (EDNRB) gene. Researchers at University of California, San Diego School of Medicine now find that mice with lower-than-normal levels of EDNRB protein are remarkably tolerant to hypoxia.

Consistent with this idea, previous studies have identified genetic variants in Tibetan highlanders associated with reduction in hemoglobin levels, an advantageous phenotype at high altitude. To compare the genetic bases of adaptations to high altitude, we collected genetic and epigenetic data in Ethiopians living at high and low altitude, respectively.

Genomic analysis of high-altitude populations residing in the Andes and Tibet has revealed several candidate loci for involvement in high-altitude adaptation, a subset of which have also been shown to be associated with hemoglobin levels, including EPAS1, EGLN1, and PPARA, which play a role in the HIF-1 pathway. Here, we have extended this work to high- and low-altitude populations living in ...

The Tibetan and Andean Plateaus and Ethiopian highlands are the largest regions to have long-term high-altitude residents. Such populations are exposed to lower barometric pressures and hence atmospheric partial pressures of oxygen. Such “hypobaric hypoxia” may limit physical functional capacity, reproductive health, and even survival.

To find out, they analyzed the genomes of nearly 260 Ethiopian villagers belonging to two ethnic groups: the Oromo, who began settling at high altitude in the Bale Mountains of southeast Ethiopia about 500 years ago, and the Amhara, who have lived at high altitude in the Semien Mountains of northwest Ethiopia for at least 5,000 years.

Approximately 2% of people worldwide live permanently at high altitudes of over 2,500 meters (1.5 miles), where oxygen is sparse, UV radiation is high, and temperatures are low. Native Andeans,...
