Study finds Nunavik Inuit are genetically unique – Medical Xpress

A new study has found that an Inuit population in Canada’s Arctic are genetically distinct from any known group, and certain genetic variants are correlated with brain aneurysm.

Geographically isolated populations often develop unique genetic traits that result from their successful adaptation to specific environments. Unfortunately, these adaptations sometimes predispose them to certain health issues if the environment is changed. The genetic background of these populations are often poorly understood because they live far from scientific research centres.

Canada’s Inuit have higher prevalence of cardiovascular disorders, as well as increased incidence of brain aneurysms, than the general population. To learn about the possible genetic origin of these disorders, researchers at The Neuro (Montreal Neurological Institute and Hospital) of McGill University analyzed the genetic characteristics of 170 Inuit volunteers from Nunavik, a region of northern Quebec. This was done with approval from Nunavik Nutrition and Health Committee in Kuujjuaq, Nunavik.
