Association of CREBRF Variants with BMI and Diabetes in Pacific Islanders

A recent genome-wide association study (GWAS) in Samoans (a Polynesian population) identified strong associations of CREBRF variants with BMI. The G allele at rs12513649 (frequency=25.8%) was associated with ∼1.3 kg/m2 higher BMI per copy, as was the Gln allele at rs373863828 (which codes for an ArgGln substitution). The Gln allele at rs373863828 has frequency of 25.9% in Samoans and is rare in most global populations, although it has been...
