Study Reveals Unique Genetic Control in Greenlanders

11/22/2025

Summary

Story summary

A study in the American Journal of Human Genetics identified 251 genetic variants that influence protein levels in Greenlanders, showing stronger genetic control than in Europeans.
IL-27 and Gal-9 account for 30–44% of their circulating levels in Greenlanders.
The work builds on Greenland's unique genetic architecture and links ancient adaptations to disease risks.
The study analyzed samples from 3,707 individuals, underscoring the need for diverse genomic research in isolated populations.
