Discoveries from genome-wide
association studies (GWAS) of metabolic phenotypes such as type 2 diabetes and
obesity only explain less than ~10% of the heritability. However, we have
recently shown that studying the historically small and isolated Greenlandic
population constitutes a unique and very valuable alternative design, which
offers increased statistical power and potential to disclose underlying
biological mechanisms. In this context, we search for variation associated with
cardiometabolic traits in the Greenlandic Inuit population with a focus on
variants which are predicted to cause loss of protein function. We are mapping
the loss of function variants through genome sequencing of the Greenlandic genome
focusing on variants which segregate at higher frequency in the Greenlandic
population than in the main populations.
