We surveyed gene–gene interactions (epistasis) in human body mass index (BMI) in four European populations (n5000). We conclude that genome-wide analysis of epistasis in multiple populations is an effective approach to provide new insights into the genetic regulation of BMI but requires additional efforts to confirm the findings.
