Meta-analysis of over 8,000 individuals from Hawai'i and Samoa for genetic associations to cardiometabolic phenotypes.

GWAS of Polynesian populations identified 25 significant trait-loci associations, including confirmation of CREBRF's link to fasting glucose, in a sample of up to 8,461 individuals.

• Why it matters: Underrepresentation of Polynesian populations in genetic studies limits understanding of population-specific genetic factors influencing cardiometabolic traits, hindering targeted health interventions.
• What they did: Researchers conducted the first GWAS in Native Hawaiians and Samoans using an updated imputation panel, analyzing 13 traits across a combined sample of up to 8,461 individuals, identifying 25 significant loci.
• The result: The study confirmed the CREBRF variant's association with fasting glucose and identified four potentially novel loci for BMI, LDL, and waist-hip ratio, though these were not replicated elsewhere, highlighting the need for larger cohorts and improved references.
