Summary

This population genetics study characterised the fine-scale genetic structure of Sherpa and neighbouring Nepalese ethnic groups across the Eastern Himalayan region. Using genotype data from 1245 individuals across Nepal and surrounding areas, the authors identified clear population substructure that broadly mirrors geographical features, with the Sherpa emerging as a remarkably isolated population showing little gene flow from surrounding Nepalese groups. The findings demonstrate that Himalayan plateau populations have had measurable impact on the Northern Indian gene pool, with groups such as Rai, Magar and Tamang showing greater proportions of Tibetan ancestry.

UK applicability

This population genetics study has limited direct applicability to UK farming systems, soil health or nutrition research. It may be of interest to UK researchers investigating human adaptation to high altitude or population health genomics in mountainous regions, but does not address food production or dietary outcomes.

Key measures

Principal component analysis, ancestry admixture proportions, homozygosity patterns, genetic differentiation across populations

Outcomes reported

The study characterised fine-scale genetic population structure across Eastern Nepal and the greater Himalayan region using dense genotype data from 1245 individuals. It identified distinct genetic substructure among Nepalese ethnic groups and quantified differential ancestry proportions from northern Himalayan populations.
